Note 20. Output voltage is proportional to AVDD voltage. Vout = (LOP)
(LON) = 1.2 x AVDD (typ).
Note 21. Load Capacitance for VSS1.
Note 22. Maximum Input voltage which analog output does not clip is proportional to AVDD voltage. Vin = 0.6 x AVDD
(typ).
Note 23. Maximum Input voltage which analog output does not clip is proportional to AVDD voltage. Vin = (IN4+)
(IN4
