Overview

The TAS5753MD evaluation module showcases the latest TI digital input Class-D open-loop amplifiers.
The TAS5753MD is an I²S input Class-D amplifier with audio processing features and integrated
headphone/line driver.

The EVM is configured in

Two-Device 2.1

mode with one stereo device using bridge tied load for left and

right channels and one mono device configured for mono applications, such as higher power full-range
speakers or subwoofers. The device operating in stereo mode has the headphone/line driver option
available via a 3.5-mm plug connector. The EVM is used in conjunction with the PurePath Console
Motherboard (PPCMB). The PVDD supply is input on the EVM daughter card, which passes it to the
PPCMB motherboard through the J4 connector. Regulators on the PPCMB create the 3.3-V power supply,
which is sent back to the DUT through the J4 connector. The EVM is controlled by PPC3 software.
