TLV320AIC3100: Can SPKVDD left unconnected if class D amp is not used?

Yee Yong Teo

Hi,

Can SPKVDD left unconnected if class D amp is not used? What other power supply rail can be disconnected if class D amp is not used?

Thanks.

YY,

No, you must connect SPKVDD. You can leave the Class-D amp powered down and muted, but the supply must be connected.

best regards,
