GENERAL DESCRIPTION

100

The AD822 is a dual precision, low power FET input op amp

that can operate from a single supply of 5 V to 30 V or from

dual supplies of ±2ꢀ5 V to ±±5 ꢀ It has true single-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 modeꢀ Output voltage swing extends

to within ±0 mV of each rail, providing the maximum output

dynamic rangeꢀ

Offset voltage of 800 μV maximum, offset voltage drift of 2 μV/°C,

input bias currents below 25 pA, and low input voltage noise

provide dc precision with source impedances up to a gigaohmꢀ

The ±ꢀ8 MHz unity-gain bandwidth, –93 dB total harmonic

distortion (THD) at ±0 kHz, and 3 V/μs slew rate are provided

with a low supply current of 800 μA per amplifierꢀ
