1 Overview

This EVM demonstrates the TAS5721DCA or TAS5723DCA integrated circuit power stage from Texas

Instruments.

The TAS5721 and TAS5723 are efficient digital audio class D power amplifiers for driving bridge-tied

speakers. Both the TAS5721 and TAS5723 drive 10-W stereo operation. Both devices also support 2.1

mode, with two SE outputs and one BTL output, 2 × 10 W + 1 × 15 W operation. The TAS5721 has

support for an additional headphone output. Review the device’s data sheets at www.ti.com for detailed

information about the TAS5721 and TAS5723.

Together with a TI Input-USB Board 3, this EVM provides a complete stereo digital audio amplifier system

which includes digital input (SPDIF), analog inputs, interface to PC and Digital Audio Processing (DAP)

features like digital volume control, input and output mixers, loudness, EQ filters and dynamic range

compression (DRC). The EVM software facilitates evaluation by providing access to the TAS5721 and

TAS5723 registers through a USB port.

NOTE: The TAS5721-TAS5723EVM is shipped with the current version of TAS5721 installed.

Evaluate the current version of TAS5723 by going to the product folder at www.ti.com and

requesting a free sample; replace TAS5721 with TAS5723.
