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 I
2
S and
I
2
C interface. To use this board it is mandatory to
use the APWorkbench software tool.
