Overview

The TAS2557EVM evaluation module provides users with a powerful tool kit for complete assessment of the TAS2557 audio amplifier when used with PurePath™ Console 3 software suite (PPC3). The evaluation module ships with an attached reference speaker. The board provides an USB connection to your PC and is controlled PPC3 software suite. PPC3 must be downloaded separately. With PPC3 you can further fine-tune the solution to your liking. Connect two EVMs together and the solution quickly transforms into a stereo solution.

The EVM also includes a connection to the Smart Amplifier Learning Board v2 where additional speakers can be characterized for your application while using the advanced features of PPC3.
