Texas Instruments TAS8501EVM Evaluation Module
Texas Instruments TAS8501EVM Evaluation Module supplies a flexible platform for evaluating the TAS8501 digital-input Class-D audio amplifier in mono or dual-mono configurations. An onboard MCU enables USB audio and I2C control through PurePath Console 3, while external I2C and I2S/TDM connections support host processors and audio test equipment.
Designed for single-cell battery evaluation, the Texas Instruments module uses an onboard boost converter to supply both amplifier channels and can accept external power rails for other configurations. Two modules can be interconnected to evaluate as many as four audio channels. Target applications include mobile phones, tablets, wearables, smart speakers with voice assistance, and wireless speakers.
