NAME
Input A Differential Mode. Configures the input A channel as either a mono differential
signal (INA = INA2 - INA1) or as a stereo signal (INA1 = left, INA2 = right).
0 = Stereo single-ended
1 = Differential
Input B Differential Mode. Configures the input B channel as either a mono differential
signal (INB = INB2 - INB1) or as a stereo signal (INB1 = left, INB2 = right).
0 = Stereo single-ended
1 = Differential
Input A Preamp Gain. Set the input gain to maximize output signal level for a given input
signal range to improve the SNR of the system. PGAINA = 111 switches to a trimmed
20kI feedback resistor for external gain setting.
