AD822BR Datasheet PDF - ADI

●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. Output voltage swing extends to within 10 mV of each rail, providing the maximum

●output dynamic range.
