Description

Trademarks

1 Description

The TAS2770 is a mono digital input Class-D audio amplifier optimized for efficiently driving high peak power into small loudspeakers. The Class-D amplifier is capable of delivering 18.3 W of peak power into a 4 Ω load while sustaining 1 % THD+N at a battery voltage of 13.8 V. Integrated speaker voltage and current sense provides for real time monitoring of loudspeaker behavior. Up to eight devices can share a common bus via either I2S/TDM + I2C or SoundwireSM interfaces. Two PDM inputs are provided for low latency playback or sensor aggregation.

The TAS2770EVM-STEREO supports evaluation and development with the TAS2770 device through the following interfaces:

• USB interface – TAS2770 control through PurePath™ Console 3 (PPC3) GUI, USB-HID – USB-class audio device, compatible with Microsoft® Windows® 7+

• Digital audio AP and PSIA interface through 100-mil headers

• I2C interface for TAS2770 control

• SoundwireSMinterface for TAS2770 control

Amplifier power supply (VBAT) 4.5 V to 16 V EVM power supply 4.5 V to 16 V IO power supply (IOVDD) 1.65 V to 1.95 V Output Power 18.3 W USB, USB class-audio Micro-USB B

3 Software

The TAS2770EVM-STEREO can be easily configured with PurePath ™ Console 3 running the TAS2770 plug-in.

Please refer to the TAS2770 PurePath Console User’s guide for detailed descriptions of the software features.

NOTE: The evaluation driver currently distributed for use with this EVM will periodically inject a tone

into the data stream. This behavior is intentional for this version of the driver. Legal procurement of the full release version of this driver is in process which will resolve this issue. As soon as it is available it will be provided to the end user.

4 Stereo Setup

1. Install PurePath™ Console 3 with the TAS2770EVM-STEREO plug-in

2. Connect the first speaker to J10 on the EVM. Alternatively, J23 and J24 can be used for speaker connections.

3. Connect a second speaker to J29 on the EVM. Alternatively, J28 and J30 can be used for speaker connections.

4. Attach a power supply to connector J9. There is also an alternate barrel jack connector (J19) adjacent to this connector.

5. Set jumper J13 to select the desired I2C address for channel 1.

6. Set jumper J31 to select the desired I2C address for channel 2.

6 Multi-Channel Setup

1. Install PurePath™ Console 3 with the TAS2770EVM-STEREO plug-in

2. Connect up to 4 TAS2770EVM-STEREOs together using connectors J5 and J7.

3. Attach a power supply to each board.

4. The leftmost board should have jumpers set to match the Stereo configuration. On all other boards insert a jumper on J2 and J6. See Figure 5 for details.

5. Set Jumpers J13 and J31 on each board to a unique address.

6. Configure the sampling rate and bit depth as discussed in Mono Setup steps 6-8.

7. Proceed to configure the device using PPC3.

8. Connect the leftmost EVM to a Windows® 7+ PC with a micro-USB cable (J16).

Digital Audio Interfaces

www.ti.com

7 Digital Audio Interfaces

The various digital audio interfaces on the TAS2770 Reference Board can be selected through hardware settings and software settings. Several headers close to the TAS2770 device allow access to the following digital audio signals:

• I2S Data out(SDOUT) from the TAS2770 (for example, current and voltage sense data)

• I2S Data in(SDIN) to the TAS2770

• I2S Word clock or fram sync(FSYNC)

• I2S Bit clock(SBCLK)

• PDM Clock (PDMCLK0) – optional input source for TAS2770

• PDM Clock (PDMCLK1) – optional input source for TAS2770

• PDM Data (PDMD0) – optional input source for TAS2770

• PDM Data (PDMD1) – optional input source for TAS2770

• I2C Clock (SCLK)

• I2C Data (SDA) TAS2770 can be configured for SoundwireSM Mode as well:

• SoundwireSM clock - SBCLK

• SoundwireSM data - SDOUT

• SoundwireSM address – SDA

• SoundwireSM address – FSYNC

• SoundwireSM address – SCL

A jumper inserted in the SW slot of J13 sets the TAS2770 to SoundwireSM mode. Then J11 can be set as desired to configure the device address.

The selection between USB (internal) and External inputs is controlled by jumpers J2 and J6. These jumpers set TDM and I2C respectively.

7.1 Digital Audio Interface Selection

7.1.1 USB

The TAS2770 Reference Board contains an XMOS microcontroller that acts as a USB HID and USBclass audio interface. To select USB, remove jumpers J6 and J2. Insert a jumper in J12. This is shown in Figure 6.

Digital Audio Interfaces

7.1.2 Direct (AP/PSIA)

Insert a jumper on J2 and connect the external digital audio source (for example AP or PSIA) to the external input header pin. The odd numbered pins on this header provide a ground for each signal. This is shown in Figure 9. Note that the jumper setting for J1 must reflect the logic level of the external source.
