GENERAL DESCRIPTION

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 ±2.5 V to ±15 V. 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 mode. Output voltage swing extends

to within 10 mV of each rail, providing the maximum output

dynamic range.

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 gigaohm.

The 1.8 MHz unity-gain bandwidth, –93 dB total harmonic

distortion (THD) at 10 kHz, and 3 V/µs slew rate are provided

with a low supply current of 800 µA per amplifier.
