Texas Instruments  TAS5825MEVM

The TAS5825MEVM showcases the latest TI digital input Class-D closed loop amplifier, TAS5825M,  with up to 192kHz sampling and extended processing. The EVM is used in conjunction with the PurePath Console Motherboard (PUREPATH-CMBEVM) and the PurePath Console 3 Software (PUREPATHCONSOLE). There are two TAS5825M devices on the EVM, allowing the user to evaluate the system in mono, stereo, or 2.1 output configurations with various process flows.  The PVDD supply is provided via the TAS5825MEVM and is regulated to 5 VDC and 3.3 VDC on the PUREPATH-CMBEVM. The PUREPATH-CMBEVM provides the I2S, I2C, and 3.3 VDC to the TAS5825MEVM.
