Rail To Rail Input Op Amp. Rail to rail op amps analog devices high speed 50 mhz rail to rail op amps enable you to operate at lower supply voltages swing closer to the rails and provide wider dynamic range. 120 µa per amplifier.

Amplifier can be used in open loop or as comparator. The most common topology has a single differential input stage using pmos as the first transistors at the input terminals. 120 µa per amplifier.
But for non inverting configuration some input common mode voltage swing is required especially for a voltage follower which usually works as an output buffer we need a rail to railinput common mode voltage range.
It has true sin gle supply capability with an input voltage range extending below the negative rail allowing the ad822 to accommodate input signals below ground while in the single supply mode. The most common topology has a single differential input stage using pmos as the first transistors at the input terminals. Amplifier can be used in open loop or as comparator. 120 µa per amplifier.
