TAS2770EVM: Mono, 18.3W @ 4Ω, Digital Input, Class-D, IV Sense Audio Amplifier

Summary

The TAS2770EVM provides developers with a simple to use mono evaluation module that can be configured as a stereo solution and as a multi-channel solution. It is powerful tool kit for assessing stereo and mono implementations of the TAS2770 with or without IV sense. Everything needed for evaluating TAS2770 is provided. A stereo or mono speaker protection solution can be evaluated by connecting a TAS2559YZEVM to provide the speaker protection algorithm and processing. The algorithm is controlled and tuned using PPC3. The TAS2559YZEVM and PPC3 add-in are not included and must be ordered separately.

Features:

Stereo or Mono evaluation mode USB input
Connect up to eight boards
Interface to TAS2559YZEVM for speaker protection evaluation
Access to TAS2770 add-in PurePath Console 3
