1 Overview
The TAS5727EVM evaluation module demonstrates the TAS5727 device from Texas Instruments. The
TAS5727 combines a high-performance PWM processor with a class-D audio power amplifier. This EVM
can be configured with two bridge-tied loads (BTL) (2.0). For detailed information about the TAS5727EVM
device, review the (device data sheet SLOS637). The Pulse Width Modulator (PWM) is based on TI's
Equibit™ technology. The TAS5727 has additional audio processing features like 3D, Bass Boost and
2-band DRC.
The EVM software, with its graphic user interface (GUI), facilitates evaluation by providing access to the
TAS5727EVM registers through a USB port. See the Using the EVM Software section for further details.

The EVM together with other TI components on this board, is a complete 2.0-channel digital audio
amplifier system. The MC57XXPSIA Controller board includes a USB interface, a digital input (SPDIF),
analog inputs via the ADC, power inputs, and other features like a mute function and power down.
