STA350BW Sound Terminal™ 2.1-channel high-efficiency digital audio system board

STEVAL-CCA030V1

Overview

The STEVAL-CCA030V1 demonstration board is based on the STA350BW Sound Terminal digital amplifier and is an integrated solution for digital audio processing, digital amplifier control and FFX®-power output stage.

The STEVAL-CCA030V1 is made up of two boards: STA350BW to evaluate the device and APWLink (STEVAL- CCA035V1) used as I²S and I²C interface. To use this board it is mandatory to use the APWorkbench software tool.
