The TAS5705 evaluation module (TAS5705EVM2) demonstrates the TAS5705 device from Texas
Instruments.
The TAS5705 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). When operated with an external subwoofer
power stage such as the TAS5601EVM4. TAS5705 supports two bridge-tied channels plus a bridge-tied
subwoofer using an external TAS5601amplifier.For detailed information about the TAS5705 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.
The EVM software with its graphic user interface facilitates evaluation by providing access to the TAS5705
registers through a USB port. Refer to the Using the EVM Software section for further details.
