The AD822ARZ is a rail to rail, FET input dual op amp (Operational Amplifier) in 8 pin NSOIC package. This dual precision, low power op amp can operate from single supply of 5V to 30V or dual supplies of ±2.5V to ±15V. It has true single supply capability with an input voltage range extending below negative rail allowing the AD822 to accommodate input signals below ground in single supply mode. Output voltage swing extends to within 10mV of each rail providing the maximum output dynamic range.
GENERAL DESCRIPTION The AD822 is a dual precision, low power FET input op amp that can operate from a single supply of 3.0 V to 36 V or dual supplies of ±1.5 V to ±18 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 in the single-supply mode.

The AD822BRZ is a Single Supply Rail-to-rail Low Power FET-input Operational Amplifier that can operate from a single supply of 5 to 30V or from dual supplies of ±2.5 to ±15V. 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 10mV of each rail, providing the maximum output dynamic range. Offset voltage of 800µV maximum, offset voltage drift of 2µV/°C, input bias currents below 25pA and low input voltage noise provide DC precision with source impedances up to a Giga ohm. The 1.8MHz unity-gain bandwidth, -93dB total harmonic distortion (THD) at 10kHz and 3V/µs slew rate are provided with a low supply current of 800µA per amplifier.
