AD2S: Differential Amplifier Selector (MUX3 and MUX4)
Default value: 0
The PCM3793/94 has stereo single-input amplifiers (PG1, PG2) and a monaural differential-input amplifier (D2S)
which can be used as ADC inputs. MUX3 and MUX4 can be selected as the monaural differential input by
setting AD2S = 1.
AD2S = 0
