AD2S: Differential Amplifier Selector (MUX3 and MUX4)
Default value: 0
The PCM3793A/94A has stereo single-input amplifiers (PG1, PG2) and a monaural differential-input amplifier
(D2S) which can output signals to the ADC. MUX3 and MUX4 can be selected as the monaural differential input
by setting AD2S = 1.
AD2S = 0
AD2S = 1

Differential-input amplifier
AIL[1:0]: AIN1L, AIN2L, and AIN3L Selector (MUX1)
Default value: 00
These bits are used to select one of the three analog inputs, AIN1L, AIN2L, or AIN3L.
