7.3.4 Rail-to-Rail Input

The OPA365-Q1 product family features true rail-to-rail input operation, with supply voltages as low as ±1.1 V (2.2 V). A unique zero-crossover input topology eliminates the input offset transition region typical of many rail-to-rail, complementary stage operational amplifiers. This topology also allows the OPA365-Q1 device to provide superior common-mode performance over the entire input range, which extends 100 mV beyond both power-supply rails, as shown in Figure 7-4. When driving ADCs, the highly linear VCM range of the OPA365-Q1 device assures that the operational amplifier/ADC system linearity performance is not compromised.
