8.3.1 Rail-to-Rail Input

The OPAx365 product family features true rail-to-rail input operation, with supply voltages as low as ±1.1 V
(2.2 V). A unique zerø-crossover input topology eliminates the input offset transition region typical of many rail-to-rail, complementary stage operational amplifiers. This topology also allows the OPAx365 to provide excdellent common-mode performance over the entire input range, which extends 100 mV beyond both power-supply rails, as shown in Figure 8-1. When driving ADCs, the highly linear VCM range of the OPAx365 makes sure that the op amp or ADC system linearity performance is not compromised.
