Once all the jumpers on the EVM are properly configured, follow the steps below:

  • Connect AC-MB to EVM by placing the EVM on top of the edge of the AC-MB.
  • Set the IOVDD jumper on AC-MB to either 3.3V or 1.8V.
  • Connect USB cable from PC to AC-MB.
  • Connect 5V power adapter to barrel jack J21 on TAS2118EVM.

  • Configure TAS2118 registers with PurePath Console (PPC3).

At this moment, the device is powered up and running, ready to play audio. The evaluation kit works as any other sound card, select the EVM as system playback device and use any software like web browser, media player, and so forth.
