VCCA and VCCD are connected together. VSSA, VSSAD and VSSD are connected together.
REC, PLAYL, PLAYE must be at VCCD
REC, PLAYL and PLAYE are forced to specified condition.

Balanced input signal applied between MIC and MIC REF as shown in the applications example. Single-
ended MIC or MIC REF recommended to be less than 100 mV peak to peak.
