Note 10. The voltage difference between IN1/2+ and IN1/2
pins. AC coupling capacitor should be inserted in series at
each input pin. Full-differential mic input is not available at MGAIN2-0 bits = “000”. Maximum input voltage of
IN1+, IN1
, IN2+ and IN2
pins is proportional to AVDD voltage, respectively.
Vin = |(IN1/2+)
