STEVAL-CCA049V1 STMicroelectronics

STEVAL-CCA049V1 STA335ML Sound Terminal 2-channel microless high efficiency digital audio system board Data brief Features 2 x 20 W into 8 = 18 V 5 V to 26 V operating supply voltage range 30 V absolute maximum rating DDXR 100 dB dynamic range Selectable 32 kHz to 48 kHz input sample rates Automatic zero-detect mute 2 2-channel I S input data interface 2 volume selection (0 and +24 dB) 2 master clock selection (256 or 364 * fs) 2 2 digital format selection (I S and LSB) RoHS compliant Description The STEVAL-CCA049V1 demonstration board is based on the STA335ML 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 STA335ML, the STEVAL- CCA049V1 does not require a microcontroller, 2 and it accepts the universal I S format. However, the board may be connected to APWlink 2 (STEVAL-CCA035V1) as I S interface.
