Note 11. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD(typ).
Note 12. When ALC2 Gain is changed, this typical value changes between 22kΩ and 26kΩ.
Note 13. Output Voltage is proportional to AVDD voltage. Vout = 0.588 x AVDD(typ).
Note 14. When the output pin drives a capacitive load, a resistor should be added in series between the output pin and
Note 15. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD(typ).
