Note 26. The Output voltage is proportional to the AVDD voltage. Vout = (LOP) − (LON) = 1.2 x AVDD (typ).
Note 27. VSS1 load capacitance to output pins.
Note 28. The Maximum Input voltage is proportional to the AVDD voltage. Vin = 0.6 x AVDD (typ).
Note 29. The Maximum Input voltage is proportional to the AVDD voltage. Vin = (IN4+) − (IN4−) = 0.6 x AVDD (typ).
Note 30. Vout = (RCP) − (RCN) at RCV bit = “1”, Vout = (LOP) − (LON) at LODIF bit = “1”.
