This user’s guide describes the operation of the evaluation module for the TAS5613 150W (TAS5611
125W) Stereo Feedback Analog-Input Digital Amplifiers from Texas Instruments. The user’s guide also
provides measurement data and design information including the schematic, BOM, and PCB layout.
The TAS5611/13PHD2EVM PurePath™ Premier Pro customer evaluation module demonstrates the
integrated circuit TAS5611 or TAS5613PHD from Texas Instruments (TI).
The TAS5611 and TAS5613PHD is high-performance, integrated Stereo Feedback Analog-Input Digital
Amplifier Power Stages designed to drive 4Ω speakers at up to 150W per channel for TAS5613PHD and
125W per channel for TAS5611PHD. This amplifier requires only a simple passive demodulation filter to
deliver high-quality, high-efficiency audio amplification.
This EVM is configured with 2 BTL channels and the possibility to apply either a single ended or a
differential analog input signal. It is also possible to configure the two BTL channels into one parallel BTL
(PBTL) channel.
The OPA1632 is a High Performance Fully Differential Audio Op Amp designed to allow operation with
single ended or differential input signals to the EVM.
This EVM stuffed with either TAS5611PHD or TAS5613PHD is a complete stereo analog input power
amplifier ready for evaluation and great music.

1.2PCB Key Map
Physical structure for the TAS5611/13PHD2EVM is illustrated in Figure 2.
This chapter describes the TAS5611/13PHD2EVM board in regards to power supply and system
interfaces. The chapter provides information regarding handling and unpacking, absolute operating
conditions, and a description of the factory default switch and jumper configuration.
This section provides a step–by–step guide to configuring the TAS5611/13PHD2EVM for device
evaluation
2.1Electrostatic Discharge Warning
Many of the components on the TAS5611/13PHD2EVM are susceptible to damage by electrostatic
discharge (ESD). Customers are advised to observe proper ESD handling precautions when unpacking
and handling the EVM, including the use of a grounded wrist strap at an approved ESD workstation.
Failure to observe ESD handling procedures may result in damage to EVM
components.
2.2Unpacking the EVM
On opening the TAS5611/13PHD2EVM package, ensure that the following items are included:
•1 pc. TAS5611/13PHD2EVM board using one TAS5611PHD or one TAS5613PHD.
If any of the items are missing, contact the Texas Instruments Product Information Center nearest you to
inquire about a replacement.
Quick Setup Guide
CAUTION
2.3Power Supply Setup
To power up the EVM, one power supply are needed. An onboard switched voltage regulator is supplying
system power, logic and gate-drive. Power supply is connected to the EVM using connector J15.
NOTE: While powering up set switch SW11 to the RESET position.
NOTE: If a single ended input signal is applied please insert jumpers in the header J24 and J25.
2.5Speaker Connection
Both positive and negative speaker outputs are floating and may not be
connected to ground (e.g., through an oscilloscope).
www.ti.com
CAUTION
2.6Output configuration BTL and PBTL
When changing mode e.g. from BTL to PBTL make sure that RESET switch (SW11) is activated before
changing the state of mode switches SW1 and SW2. Switch SW1 and SW2 has to be synchronized in
state BTL or PBTL.
Input signal to RCA connector J20 when operating PBTL mode. J21 is disabled.
In PBTL mode, the load has to be connected according to Figure 3:
This section describes the short-circuit protection and fault-reporting circuitry of the TAS5611 and
TAS5613 devices.
3.1Short-Circuit Protection and Fault-Reporting Circuitry
The TAS5611 and TAS5613 is self-protecting devices that provides fault reporting (including
high-temperature protection and short-circuit protection). TAS5611 and TAS5613 is configured in
back-end auto-recovery mode, and therefore; resets automatically after all errors (M1, M2, and M3 is set
low); see the data sheet (SLAS681) (SLAS676) for further explanation. This mean that the device restart
itself after an error occasion and report through the SD error signal.
The OTW and SD outputs from TAS5611/13 indicate fault conditions. See the
TAS5611PHD/TAS5613PHD data manual for a description of these pins.
Table 3. TAS5611/13 Warning/Error Signal Decoding

101100°C temperature warning
111Normal operation, no errors/warnings
The shutdown signals together with the temperature warning signal give chip-state information as
described in the Table 3. device fault-reporting outputs are open-drain outputs.

FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and
can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this
equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.
EVM Warnings and Restrictions
It is important to operate this EVM within the input voltage range of 0 V to 32.5 V for the TAS5611; 0 V to 36 V for the TAS5613
and the output voltage range of 0 V to 32.5 V for the TAS5611; 0 V to 36 V for the TAS5613.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 90°C. The EVM is designed to
operate properly with certain components above 125°C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.
