Note 13. BEEP-AMP can’t output more than this maximum voltage.
Note 14. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD.
Note 15. When ALC2 Gain is changed, this typical value changes between 22k and 26k .
Note 16. Output Voltage is proportional to AVDD voltage. Vout = 0.588 x AVDD.
Note 17. When the output pin drives a capacitive load, a resistor should be added in series between the output pin and
