Description

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.
