8.3.1 Rail-to-Rail Input

The OPA363 and OPA364 feature excellent rail-to-rail operation, with supply voltages as low as ±0.9 V. The input common-mode voltage range of the OPA363 and OPA364 family extends 100 mV beyond supply rails. The unique input topology of the OPA363 and OPA364 eliminates the input offset transition region typical of most rail-to-rail, complementary stage operational amplifiers, allowing the OPA363 and OPA364 to provide superior common-mode performance over the entire common-mode input range, as seen in Figure 21. This feature prevents degradation of the differential linearity error and THD when driving A/D converters. A simplified schematic of the OPA363 and OPA364 is shown in the Functional Block Diagram.
