Note 12. 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 MGAIN1-0 bits = “00”. Maximum input voltage of
IN1+, IN1
, IN2+ and IN2
pins is proportional to AVDD voltage, respectively.
Vin = 0.069 x AVDD (max)@MGAIN1-0 bits = “01”, 0.035 x AVDD (max)@MGAIN1-0 bits = “10”, 0.017 x
AVDD (max)@MGAIN1-0 bits = “11”.
When the signal larger than above value is input to IN1+, IN1
, IN2+ or IN2
pin, ADC does not operate
normally.
Note 13. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD (typ)
Note 14. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD (typ)@MGAIN1-0 bits = “01” (+20dB),
Vin = 0.6 x AVDD(typ)@MGAIN1-0 bits = “00” (0dB)
Note 15. MGAIN1-0 bits = “01” (+20dB)
Note 16. MGAIN1-0 bits = “00” (0dB)
