STA333ML Sound Terminal® 2-channel microless high efficiency digital audio system board
  • active Active

The STEVAL-CCA048V1 demonstration board is based on the STA333ML Sound Terminal® digital amplifier. It provides full digital audio streaming to the speakers and offers cost effectiveness, low power dissipation, sound enrichment and DDX® power output stage.

To evaluate the STA333ML, the STEVAL-CCA048V1 does not require a microcontroller, and it accepts the universal I2S format. However, the board may be connected to APWlink (STEVAL-CCA035V1) as I2S interface.
