6.18 ADC/Input Path Control (Address 14h)
6.18.1 PGA x Input Select
Selects the specified analog input signal into channel x’s PGA.
Note: For pseudodifferential inputs, the CODEC automatically chooses the respective pseudoground
(LINEIN_REF or MIC1_REF, LINEIN_REF or MIC2_REF) for each input selection.
6.18.2 Boost x
Configures a +20 dB digital boost on channel x.
6.18.3 Invert ADCx Signal Polarity
Configures the polarity of the ADC channel x signal.
