The TAS5622-TAS5624DDVEVM PurePath™ EVM demonstrates the most recent version of TAS5622DDV or TAS5624DDV integrated circuit power stage. TAS5622 and TAS5624 are high-performance, integrated Stereo Feedback Digital Amplifier Power Stages designed to drive 3Ω speakers at up to 165W per channel for TAS5622 and 200W per channel for TAS5624. They require only passive demodulation filters to deliver efficient high quality audio amplification.
The EVM can be configured as 2 BTL channels for stereo evaluation or 1 PBTL (parallel BTL) channel for subwoofer evaluation. Together with a TI Input-USB Board 3, it provides a complete stereo digital audio amplifier system which includes digital input (S/PDIF), analog inputs, interface to PC and DAP features like digital volume control, input and output mixers, automute, tone controls, loudness, EQ filters and dynamic range compression (DRC). There are configuration options for power stage failure protection.
