1Overview

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.
