3 Description
The TAS5733L device is an efficient, digital-input audio amplifier for driving stereo speakers configured as a bridge tied load (BTL). In parallel bridge tied load (PBTL) in can produce higher power by driving the parallel outputs into a single lower impedance load. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers.
The TAS5733L device is a slave-only device receiving all clocks from external sources. The TAS5733L device operates with a PWM carrier between a 384-kHz switching rate and a 288-kHz switching rate, depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.

(1) For operation at PVDD levels greater than 14.5 V, the modulation limit must be set to 96.1% or lower via the control port register 0x10. (2) 16.5 V is the maximum recommended voltage for continuous operation of the TAS5733L device. Testing and characterization of the
device is performed up to and including 16.5 V to ensure “in system” design margin. However, continuous operation at these levels is not recommended. Operation above the maximum recommended voltage may result in reduced performance, errant operation, and reduction in device reliability.

7 Detailed Description
7.1 Overview
The TAS5733L device is an efficient, digital-input audio amplifier for driving stereo speakers configured as a bridge tied load (BTL). In parallel bridge tied load (PBTL) in can produce higher power by driving the parallel outputs into a single lower impedance load. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers.
The TAS5733L device is a slave-only device receiving all clocks from external sources. The TAS5733L device operates with a PWM carrier between a 384-kHz switching rate and a 288-kHz switching rate, depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.

7.4 Feature Description
7.4.1 Clock, Autodetection, and PLL
The TAS5733L device is an I²S slave device. The TAS5733L device accepts MCLK, SCLK, and LRCK. The digital audio processor (DAP) supports all the sample rates and MCLK rates that are defined in the Clock Control
Register.
The TAS5733L device checks to verify that SCLK is a specific value of 32 fS, 48 fS, or 64 fS. The DAP only supports a 1 × fSLRCK. The timing relationship of these clocks to SDIN is shown in subsequent sections. The clock section uses MCLK or the internal oscillator clock (when MCLK is unstable, out of range, or absent) to produce the internal clock (DCLK) running at 512 times the PWM switching frequency.
The DAP can autodetect and set the internal clock control logic to the appropriate settings for all supported clock rates as defined in the Clock Control Register.
The TAS5733L device has robust clock error handling that uses the built-in trimmed oscillator clock to quickly detect changes/errors. Once the system detects a clock change/error, the system mutes the audio (through a single-step mute) and then forces PLL to limp using the internal oscillator as a reference clock. Once the clocks are stable, the system autodetects the new rate and reverts to normal operation. During this process, the default volume is restored in a single step (also called hard unmute). The ramp process can be programmed to ramp back slowly (also called soft unmute) as defined in the Volume Configuration Register.
7.4.2 PWM Section
The TAS5733L DAP device uses noise-shaping and customized nonlinear correction algorithms to achieve high power efficiency and high-performance digital audio reproduction. The DAP uses a fourth-order noise shaper to increase dynamic range and SNR in the audio band. The PWM section accepts 24-bit PCM data from the DAP and outputs two BTL PWM audio output channels.
The PWM section has individual-channel dc-blocking filters that can be enabled and disabled. The filter cutoff frequency is less than 1 Hz.
The PWM section has an adjustable maximum modulation limit of 93.8% to 99.2%. For PVDD > 14.5 V the modulation index must be limited to 96.1% for safe and reliable operation.
7.4.3 PWM Level Meter
The structure in Figure 29 shows the PWM level meter that can be used to study the power profile.
7.4.4 Automatic Gain Limiter (AGL)
The AGL scheme has three AGL blocks. One ganged AGL exists for the high-band left/right channels, the mid­band left/right channels, and the low-band left/right channels.
The AGL input/output diagram is shown in Figure 30.

7.4.5 Fault Indication
ADR/FAULT is an input pin during power up. This pin can be programmed after RST to be an output by writing 1 to bit 0 of I²C register 0x05. In that mode, the ADR/FAULT pin has the definition shown in Table 2.
Any fault resulting in device shutdown is signaled by the ADR/FAULT pin going low (see Table 2). A latched version of this pin is available on D1 of register 0x02. This bit can be reset only by an I²C write.

SLASE77A –MARCH 2016–REVISED MARCH 2016
7.4.6 SSTIMER Pin Functionality
The SSTIMER pin uses a capacitor connected between this pin and ground to control the output duty cycle when exiting all-channel shutdown. The capacitor on the SSTIMER pin is slowly charged through an internal current source, and the charge time determines the rate at which the output transitions from a near-zero duty cycle to the desired duty cycle. This allows for a smooth transition that minimizes audible pops and clicks. When the part is shut down, the drivers are placed in the high-impedance state and transition slowly down through an internal 3­kresistor, similarly minimizing pops and clicks. The shutdown transition time is independent of the SSTIMER pin capacitance. Larger capacitors increase the start-up time, while smaller capacitors decrease the start-up time. The SSTIMER pin can be left floating for BD modulation.
7.4.7 Device Protection System
7.4.7.1 Overcurrent (OC) Protection With Current Limiting
The TAS5733L device has independent, fast-reacting current detectors on all high-side and low-side power-stage FETs. The detector outputs are closely monitored to prevent the output current from increasing beyond the overcurrent threshold defined in the Protection Characteristics table.
If the output current increases beyond the overcurrent threshold, the device shuts down and the outputs transition to the off or high impedance (Hi-Z) state. The device returns to normal operation once the fault condition (i.e., a short circuit on the output) is removed. Current-limiting and overcurrent protection are not independent for half-bridges. That is, if the bridge-tied load between half-bridges A and B causes an overcurrent fault, half-bridges A, B, C, and D shut down.
7.4.7.2 Overtemperature Protection
The TAS5733L device has an overtemperature-protection system. If the device junction temperature exceeds 150°C (nominal), the device enters thermal shutdown, where all half-bridge outputs enter the high-impedance (Hi-Z) state, and ADR/FAULT asserts low if the device is configured to function as a fault output. The TAS5733L device recovers automatically once the junction temperature of the device drops approximately 30°C.
7.4.7.3 Undervoltage Protection (UVP) and Power-On Reset (POR)
The UVP and POR circuits of the TAS5733L device fully protect the device in any power-up/down and brownout situation. While powering up, the POR circuit resets the overload circuit (OLP) and ensures that all circuits are fully operational when the PVDD and AVDD supply voltages reach 7.6 V and 2.7 V, respectively. Although PVDD and AVDD are independently monitored. For PVDD, if the supply voltage drops below the UVP threshold, the protection feature immediately sets all half-bridge outputs to the high-impedance (Hi-Z) state and asserts ADR/FAULT low.
7.5 Device Functional Modes
The TAS5733L device is a digital input class-d amplifier with audio processing capabilities. The TAS5733L device has numerous modes to configure and control the device.
7.5.1 Serial Audio Port Operating Modes
The serial audio port in the TAS5733L device supports industry-standard audio data formats, including I²S, Left­justified(LJ) and Right-justified(RJ) formats. To select the data format that will be used with the device can controlled by using the serial data interface registers 0x04. The default is 24bit, I²S mode. The timing diagrams for the various serial audio port are shown in the Serial Interface Control and Timing section
7.5.2 Communication Port Operating Modes
The TAS5733L device is configured via an I²C communication port. The I²C communication protocol is detailed in the 7.7 I²C Serial Control Port Requirements and Specifications section.

Device Functional Modes (continued)
7.5.3 Speaker Amplifier Modes
The TAS5733L device can be configured as:
Stereo Mode
Mono Mode
7.5.3.1 Stereo Mode
Stereo mode is the most common option for the TAS5733L. TAS5733L can be connected in 2.0 mode to drive stereo channels. Detailed application section regarding the stereo mode is discussed in the Stereo Bridge Tied
Load Application section.
7.5.3.2 Mono Mode
Mono mode is described as the operation where the two BTL outputs of amplifier are placed in parallel with one another to provide increase in the output power capability. This mode is typically used to drive subwoofers, which require more power to drive larger loudspeakers with high-amplitude, low-frequency energy. Detailed application section regarding the mono mode is discussed in the Mono Parallel Bridge Tied Load Application section.
7.6 Programming
7.6.1 I²C Serial Control Interface
The TAS5733L device has a bidirectional I²C interface that is compatible with the Inter IC (I²C) bus protocol and supports both 100-kHz and 400-kHz data transfer rates for single- and multiple-byte write and read operations. This is a slave-only device that does not support a multimaster bus environment or wait-state insertion. The control interface is used to program the registers of the device and to read device status.
The DAP supports the standard-mode I²C bus operation (100 kHz maximum) and the fast I²C bus operation (400 kHz maximum). The DAP performs all I²C operations without I²C wait cycles.
7.6.1.1 General I²C Operation
The I²C bus employs two signals, SDA (data) and SCL (clock), to communicate between integrated circuits in a system. Data is transferred on the bus serially, one bit at a time. The address and data can be transferred in byte (8-bit) format, with the most-significant bit (MSB) transferred first. In addition, each byte transferred on the bus is acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with the master device driving a start condition on the bus and ends with the master device driving a stop condition on the bus. The bus uses transitions on the data pin (SDA) while the clock is high to indicate start and stop conditions. A high-to-low transition on SDA indicates a start and a low-to-high transition indicates a stop. Normal data-bit transitions must occur within the low time of the clock period. These conditions are shown in Figure 32. The master generates the 7-bit slave address and the read/write (R/W) bit to open communication with another device and then waits for an acknowledge condition. The TAS5733L device holds SDA low during the acknowledge clock period to indicate an acknowledgment. When this occurs, the master transmits the next byte of the sequence. Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte). All compatible devices share the same signals via a bidirectional bus using a wired-AND connection. An external pullup resistor must be used for the SDA and SCL signals to set the high level for the bus.

TAS5733L

SLASE77A –MARCH 2016–REVISED MARCH 2016
Programming (continued)
No limit exists for the number of bytes that can be transmitted between start and stop conditions. When the last word transfers, the master generates a stop condition to release the bus. A generic data transfer sequence is shown in Figure 32.
The 7-bit address for the TAS5733L device is 0101 010 (0x54) or 0101 011 (0x56) as defined by ADR/FAULT (external pulldown for 0x54 and pullup for 0x56).
7.6.1.2 I²C Slave Address
The ADR/FAULT is an input pin during power-up and after each toggle of RST, which is used to set the I²C sub­address of the device. The ADR/FAULT can also operate as a fault output after power-up is complete and the address has been latched in.
At power-up, and after each toggle of RST, the pin is read to determine its voltage level. If the pin is left floating, an internal pull-up will set the I²C sub-address to 0x56. This will also be the case if an external resistor is used to pull the pin up to AVDD. To set the sub-address to 0x54, an external resistor (specified in Typical Applications ) must be connected to the system ground.
As mentioned, the pin can also be reconfigured as an output driver via I²C for fault monitoring. Use System
Control Register 2 (0x05) to set ADR/FAULT pin to be used as a fault output during fault conditions.
I²C Device Address Change Procedure
1. Write to device address change enable register, 0xF8 with a value of 0xF9A5 A5A5.
2. Write to device register 0xF9 with a value of 0x0000 00XX, where XX is the new address.
3. Any writes after that should use the new device address XX.
7.6.1.3 Single- and Multiple-Byte Transfers
The serial control interface supports both single-byte and multiple-byte read/write operations for subaddresses 0x00 to 0x1F. However, for the subaddresses 0x20 to 0xFF, the serial control interface supports only multiple­byte read/write operations (in multiples of 4 bytes).
During multiple-byte read operations, the DAP responds with data, a byte at a time, starting at the subaddress assigned, as long as the master device continues to respond with acknowledges. If a particular subaddress does not contain 32 bits, the unused bits are read as logic 0.
During multiple-byte write operations, the DAP compares the number of bytes transmitted to the number of bytes that are required for each specific subaddress. For example, if a write command is received for a biquad subaddress, the DAP must receive five 32-bit words. If fewer than five 32-bit data words have been received when a stop command (or another start command) is received, the received data is discarded.
Supplying a subaddress for each subaddress transaction is referred to as random I²C addressing. The TAS5733L device also supports sequential I²C addressing. For write transactions, if a subaddress is issued followed by data for that subaddress and the 15 subaddresses that follow, a sequential I²C write transaction has taken place, and the data for all 16 subaddresses is successfully received by the TAS5733L device. For I²C sequential-write transactions, the subaddress then serves as the start address, and the amount of data subsequently transmitted before a stop or start is transmitted determines how many subaddresses are written. As was true for random addressing, sequential addressing requires that a complete set of data be transmitted. If only a partial set of data is written to the last subaddress, the data for the last subaddress is discarded. However, all other data written is accepted; only the incomplete data is discarded.

7.6.1.4 Single-Byte Write
As shown in Figure 33, a single-byte data-write transfer begins with the master device transmitting a start condition followed by the I²C device address and the read/write bit. The read/write bit determines the direction of the data transfer. For a data-write transfer, the read/write bit is a 0. After receiving the correct I²C device address and the read/write bit, the DAP responds with an acknowledge bit. Next, the master transmits the address byte or bytes corresponding to the internal memory address being accessed. After receiving the address byte, the TAS5733L device again responds with an acknowledge bit. Next, the master device transmits the data byte to be written to the memory address being accessed. After receiving the data byte, the TAS5733L device again responds with an acknowledge bit. Finally, the master device transmits a stop condition to complete the single­byte data-write transfer.
Figure 33. Single-Byte Write Transfer
7.6.1.5 Multiple-Byte Write
A multiple-byte data-write transfer is identical to a single-byte data-write transfer except that multiple data bytes are transmitted by the master device to the DAP as shown in Figure 34. After receiving each data byte, the TAS5733L device responds with an acknowledge bit.
Figure 34. Multiple-Byte Write Transfer
7.6.1.6 Single-Byte Read
As shown in Figure 35, a single-byte data-read transfer begins with the master device transmitting a start condition, followed by the I²C device address and the read/write bit. For the data read transfer, both a write followed by a read are actually done. Initially, a write is done to transfer the address byte or bytes of the internal memory address to be read. As a result, the read/write bit becomes a 0. After receiving the TAS5733L address and the read/write bit, TAS5733L device responds with an acknowledge bit. In addition, after sending the internal memory address byte or bytes, the master device transmits another start condition followed by the TAS5733L address and the read/write bit again. This time, the read/write bit becomes a 1, indicating a read transfer. After receiving the address and the read/write bit, the TAS5733L device again responds with an acknowledge bit. Next, the TAS5733L device transmits the data byte from the memory address being read. After receiving the data byte, the master device transmits a not-acknowledge followed by a stop condition to complete the single­byte data-read transfer.

7.6.2 Serial Interface Control and Timing
7.6.2.1 Serial Data Interface
Serial data is input on SDIN. The PWM outputs are derived from SDIN. The TAS5733L DAP accepts serial data in 16-bit, 20-bit, or 24-bit left-justified, right-justified, and I²S serial data formats.
7.6.2.2 I²S Timing
I²S timing uses LRCK to define when the data being transmitted is for the left channel and when the data is for the right channel. LRCK is low for the left channel and high for the right channel. A bit clock running at 32 × fS, 48 × fS, or 64 × fSis used to clock in the data. A delay of one bit clock exists from the time the LRCK signal changes state to the first bit of data on the data lines. The data is written MSB-first and is valid on the rising edge of bit clock. The DAP masks unused trailing data bit positions.

Figure 46. 3.23 Format
The decimal value of a 3.23 format number can be found by following the weighting shown in Figure 46. If the most significant bit is logic 0, the number is a positive number, and the weighting shown yields the correct number. If the most significant bit is a logic 1, then the number is a negative number. In the case every bit must be inverted, a 1 added to the result, and then the weighting shown in Figure 47 applies to obtain the magnitude of the negative number.
Figure 47. Conversion Weighting Factors—3.23 Format to Floating Point
Gain coefficients, entered via the I²C bus, must be entered as 32-bit binary numbers. The format of the 32-bit number (4-byte or 8-digit hexadecimal number) is shown in Figure 48.

7.7.2 Detailed Register Descriptions
7.7.2.1 Clock Control Register (0x00)
The clocks and data rates are automatically determined by the TAS5733L. The clock control register contains the autodetected clock status. Bits D7–D5 reflect the sample rate. Bits D4–D2 reflect the MCLK frequency.

7.7.2.3 Error Status Register (0x02)
The error bits are sticky and are not cleared by the hardware. This means that the software must clear the register (write zeroes) and then read them to determine if they are persistent errors.
Error definitions:
MCLK error: MCLK frequency is changing. The number of MCLKs per LRCLK is changing.
SCLK error: The number of SCLKs per LRCLK is changing.
LRCLK error: LRCLK frequency is changing.
Frame slip: LRCLK phase is drifting with respect to internal frame sync.

7.7.2.4 System Control Register 1 (0x03)
System control register 1 has several functions:
Bit D7: If 0, the dc-blocking filter for each channel is disabled.
If 1, the dc-blocking filter (–3 dB cutoff <1 Hz) for each channel is enabled.
Bit D5: If 0, use soft unmute on recovery from a clock error. This is a slow recovery. Unmute takes the
same time as the volume ramp defined in register 0x0E. If 1, use hard unmute on recovery from clock error. This is a fast recovery, a single-step volume
ramp.
Bits D1–D0: Select de-emphasis

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
8.1 Application Information
As mentioned previously, the TAS5733L device can be used in stereo and mono mode. This section describes the information required to configure the device for several popular configurations and for integrating the TAS5733L device into the larger system.
8.1.1 External Component Selection Criteria
The Supporting Component Requirements table in each application description section lists the details of the supporting required components in each of the System Application Schematics. Where possible, the supporting component requirements have been consolidated to minimize the number of unique components which are used in the design. Component list consolidation is a method to reduce the number of unique part numbers in a design. Consolidation is done to ease inventory management and reduce the manufacturing steps during board assembly. For this reason, some capacitors are specified at a higher voltage than what would normally be required. An example of this is a 50-V capacitor can be used for decoupling of a 3.3-V power supply net.
In this example, a higher voltage capacitor can be used even on the lower voltage net to consolidate all caps of that value into a single component type. Similarly, several unique resistors, all having the same size and value but different power ratings can be consolidated by using the highest rated power resistor for each instance of that resistor value.
While this consolidation can seem excessive, the benefits of having fewer components in the design can far outweigh the trivial cost of a higher voltage capacitor. If lower voltage capacitors are already available elsewhere in the design, they can be used instead of the higher voltage capacitors. In all situations, the voltage rating of the capacitors must be at least 1.45 times the voltage of the voltage which appears across them. The power rating of the capacitors should be 1.5 times to 1.75 times the power dissipated in the capacitors during normal use case.
8.1.1.1 Component Selection Impact on Board Layout, Component Placement, and Trace Routing
Because the layout is important to the overall performance of the circuit, the package size of the components shown in the component list were intentionally chosen to allow for proper board layout, component placement, and trace routing. In some cases, traces are passed in between two surface mount pads or ground plane extends from the TAS5733L device between two pads of a surface mount component and into to the surrounding copper for increased heat-sinking of the device. While components can be offered in smaller or larger package sizes, the package size should remain identical to that used in the application circuit as shown. This consistency ensures that the layout and routing can be matched very closely, optimizing thermal, electromagnetic, and audio performance of the TAS5733L device in circuit in the final system.
8.1.1.2 Amplifier Output Filtering
The TAS5733L device is often used with a low-pass filter, which is used to filter out the carrier frequency of the PWM modulated output. This filter is frequently referred to as the L-C Filter, due to the presence of an inductive element L and a capacitive element C to make up the 2-pole filter. The L-C filter removes the carrier frequency, reducing electromagnetic emissions and smoothing the current waveform which is drawn from the power supply. The presence and size of the L-C filter is determined by several system level constraints. In some low-power use cases that do not have other circuits which are sensitive to EMI, a simple ferrite bead or ferrite bead and capacitor can replace the traditional large inductor and capacitor that are commonly used. In other high-power applications, large toroid inductors are required for maximum power and film capacitors can be preferred due to audio characteristics. Refer to the application report Class-D Filter Design (SLOA119) for a detailed description of proper component selection and design of an L-C filter based upon the desired load and response.

8.2 Typical Applications
These typical connection diagrams highlight the required external components and system level connections for proper operation of the device in several popular use cases. Each of these configurations can be realized using the Evaluation Module (EVM) for the device. These flexible modules allow full evaluation of the device in the most common modes of operation. Any design variation can be supported by TI through schematic and layout reviews. Visit http://e2e.ti.com for design assistance and join the audio amplifier discussion forum for additional information.
8.2.1 Stereo Bridge Tied Load Application
A stereo system generally refers to a system inside which are two full range speakers without a separate amplifier path for the speakers that reproduce the low-frequency content. In this system, two channels are presented to the amplifier via the digital input signal. These two channels are amplified and then sent to two separate speakers.
Most commonly, the two channels are a pair of signals called a stereo pair, with one channel containing the audio for the left channel and the other channel containing the audio for the right channel. While the two channels can contain any two audio channels, such as two surround channels of a multi-channel speaker system, the most popular occurrence in two channels systems is a stereo pair.
The Stereo BTL Configuration is shown in Figure 49.

8.2.1.2.1 Component Selection and Hardware Connections
The typical connections required for proper operation of the device can be found on the TAS5733L User’s Guide. The device was tested with this list of components, deviation from this typical application components unless recommended by this document can produce unwanted results, which could range from degradation of audio performance to destructive failure of the device. The application report Class-D Filter Design (SLOA119) offers a detailed description of proper component selection and design of the output filter based upon the modulation used, desired load and response.
I²C Compliant Master GPIO Control

8.2.1.2.2 Control and Software Integration
The TAS5733L device has a bidirectional I²C used to program the registers of the device and to read device status. The TAS5733LEVM and the PurePath Console GUI are powerful tools that allow the TAS5733L evaluation, control and configuration. The Register Dump feature of the PurePath Console software can be used to generate a custom configuration file for any end-system operating mode. Prior approval is required to download PurePath Console GUI. Please request access at http://www.ti.com/tool/purepathconsole.
8.2.1.2.3 I²C Pullup Resistors
Customary pullup resistors are required on the SCL and SDA signal lines. They are not shown in the Typical Application Circuits, because they are shared by all of the devices on the I²C bus and are considered to be part of the associated passive components for the System Processor. These resistor values should be chosen per the guidance provided in the I²C Specification.
8.2.1.2.4 Digital I/O Connectivity
The digital I/O lines of the TAS5733L are described in previous sections. As discussed, whenever a static digital pin (that is a pin that is hardwired to be HIGH or LOW) is required to be pulled HIGH, it should be connected to DVDD through a pull-up resistor to control the slew rate of the voltage presented to the digital I/O pins. However, having a separate pull-up resistor for each static digital I/O line is not necessary. Instead, a single resistor can be used to tie all static I/O lines HIGH to reduce BOM count.

8.2.2 Mono Parallel Bridge Tied Load Application
A mono system refers to a system in which the amplifier is used to drive a single loudspeaker. Parallel Bridge Tied Load (PBTL) indicates that the two full-bridge channels of the device are placed in parallel and drive the loudspeaker simultaneously using an identical audio signal. The primary benefit of operating this device in PBTL operation is to reduce the power dissipation and increase the current sourcing capabilities of the amplifier output. In this mode of operation, the current limit of the audio amplifier is approximately doubled while the on-resistance is approximately halved.
The loudspeaker can be a full-range transducer or one that only reproduces the low-frequency content of an audio signal, as in the case of a powered subwoofer. Often in this use case, two stereo signals are mixed together and sent through a low-pass filter to create a single audio signal which contains the low-frequency information of the two channels.
The Mono PBTL Configuration is shown in Figure 51.

9 Power Supply Recommendations
To facilitate system design, the TAS5733L device requires only a 3.3-V supply in addition to the PVDD power­stage supply. An internal voltage regulator provides suitable voltage levels for the gate drive circuitry. Additionally, all circuitry requiring a floating voltage supply, e.g., the high-side gate drive, is accommodated by built-in bootstrap circuitry requiring only a few external capacitors.
To provide good electrical and acoustical characteristics, the PWM signal path for the output stage is designed as identical, independent half-bridges. For this reason, each half-bridge has separate bootstrap pins (BSTRP_x), and power-stage supply pins (PVDD). The gate-drive voltage (GVDD_REG) is derived from the PVDD voltage. Place all decoupling capacitors as close to their associated pins as possible. In addition, avoid inductance between the power-supply pins and the decoupling capacitors.
For a properly functioning bootstrap circuit, a small ceramic capacitor must be connected from each bootstrap pin (BSTRP_x) to the power-stage output pin (AMP_OUT_X). When the power-stage output is low, the bootstrap capacitor is charged through an internal diode connected between the gate-drive regulator output pin (GVDD_REG) and the bootstrap pin. When the power-stage output is high, the bootstrap capacitor potential is shifted above the output potential and thus provides a suitable voltage supply for the high-side gate driver. The capacitors shown in Typical Applications ensure sufficient energy storage, even during minimal PWM duty cycles, to keep the high-side power-stage FET (LDMOS) fully turned on during the remaining part of the PWM cycle.
Special attention should be paid to the power-stage power supply; this includes component selection, PCB placement, and routing. As indicated, each half-bridge has independent power-stage supply pins (PVDD). For optimal electrical performance, EMI compliance, and system reliability, each PVDD pin should be decoupled with a 100-nF, X7R ceramic capacitor placed as close as possible to each supply pin.
The TAS5733L device is fully protected against erroneous power-stage turn-on due to parasitic gate charging.

10 Layout
10.1 Layout Guidelines
Audio amplifiers which incorporate switching output stages must have special attention paid to their layout and the layout of the supporting components used around them. The system level performance metrics, including thermal performance, electromagnetic compliance (EMC), device reliability, and audio performance are all affected by the device and supporting component layout. Ideally, the guidance provided in the Application
Information section with regard to device and component selection can be followed by precise adherence to the
layout guidance shown in Figure 52. The examples represent exemplary baseline balance of the engineering trade-offs involved with laying out the device. The designs can be modified slightly as needed to meet the needs of a given application. For example, in some applications, solution size can be compromised to improve thermal performance through the use of additional contiguous copper near the device. Conversely, EMI performance can be prioritized over thermal performance by routing on internal traces and incorporating a via picket-fence and additional filtering components.
10.1.1 Decoupling Capacitors
Placing the bypassing and decoupling capacitors close to supply has been long understood in the industry. The placement of the capacitors applies to AVDD and PVDD. However, the capacitors on the PVDD net for the TAS5733L device deserve special attention. The small bypass capacitors on the PVDD lines of the DUT must be placed as close the PVDD pins as possible. Not only does placing these devices far away from the pins increase the electromagnetic interference in the system, but doing so can also negatively affect the reliability of the device. Placement of these components too far from the TAS5733L device may cause ringing on the output pins that can cause the voltage on the output pin to exceed the maximum allowable ratings shown in the Absolute Maximum Ratings table, damaging the device. For that reason, the capacitors on the PVDD net must be no further away from their associated PVDD pins than what is shown in the example layouts in the Layout Example section.
10.1.2 Thermal Performance and Grounding
Follow the layout examples shown in the Layout Example section of this document to achieve the best balance of solution size, thermal, audio, and electromagnetic performance. In some cases, deviation from this guidance may be required due to design constraints which cannot be avoided. In these instances, the system designer should ensure that the heat can get out of the device and into the ambient air surrounding the device. Fortunately, the heat created in the device naturally travels away from the device and into the lower temperature structures around the device.
Primarily, the goal of the PCB design is to minimize the thermal impedance in the path to those cooler structures. These tips should be followed to achieve that goal:
Avoid placing other heat-producing components or structures near the amplifier (including above or below in the end equipment).
Use a higher layer count PCB if possible to provide more heat sinking capability for the TAS5733L device and to prevent traces of copper signal and power planes from breaking up the contiguous copper on the top and bottom layer.
Place the TAS5733L device away from the edge of the PCB when possible to ensure that heat can travel away from the device on all four sides.
Avoid cutting off the flow of heat from the TAS5733L device to the surrounding areas with traces or via strings. Instead, route traces perpendicular to the device and line up vias in columns which are perpendicular to the device.
Unless the area between two pads of a passive component is large enough to allow copper to flow in between the two pads, orient it so that the narrow end of the passive component is facing the TAS5733L device. Because the ground pins are the best conductors of heat in the package, maintain a contiguous ground plane from the ground pins to the PCB area surrounding the device for as many of the ground pins as possible.
