Overview
The TAS5706A evaluation module (TAS5706EVM2) demonstrates the TAS5706A device from Texas
Instruments.
The TAS5706A 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) or two single-ended (SE) and one BTL sub
(2.1) or four SE (4.0) modes. When operated with an external subwoofer power stage such as the
TAS5601EVM4. TAS5706A supports two bridge-tied channels plus a bridge-tied subwoofer using an
external TAS5601amplifier.For detailed information about the TAS5706A device, review the device data
sheet, document number SLOS606. Pulse Width Modulator (PWM) is based on TI's Equibit™ technology.
Review the board schematic and TAS5601EVM4 documents for additional information, and more specific
application information on the subwoofer daughter card and connectors between the two boards.
The EVM software with its graphic user interface facilitates evaluation by providing access to the
TAS5706A registers through a USB port. Refer to the
