AD822ARZ

The AD822ARZ is one member of the AD822 series.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.

Features of the AD822ARZ are:(1)output swings rail-to-rail; (2)input voltage range extends below ground; (3)single-supply capability from 3 V to 36 V; (4)dual-supply capability from ±1.5 V to ±18 V; (5)800 A maximum quiescent current per amplifier ; (6)unity gain bandwidth: 1.8 MHz; (7)Slew rate of 3.0 V/s; (8)800 V maximum input offset voltage; (9)2 V/°C typical offset voltage drift; (10)25 pA maximum input bias current.The AD822 drives up to 350 pF of direct capacitive load as a follower and provides a minimum output current of 15 mA.This allows the amplifier to handle a wide range of load conditions. Its combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile amplifier for the single-supply user.

The absolute maximum ratings of the AD822ARZ can be summarized as:(1)supply voltage:±18 V ;(2)output short circuit duration:indefinite;(3)operating temperature range:-40 to +85;(4)storage temperature range:65 to +125;(5)lead temperature(soldering,60 sec):260;(6)differential input voltage:±30 V.Stresses above those listed under absolute maximum ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The maximum power that can be safely dissipated by the AD822 is limited by the associated rise in junction temperature.For plastic packages, the maximum safe junction temperature is 145°C.If these maximums are exceeded momentarily, proper circuit operation is restored as soon as the die temperature is reduced. Leaving the device in the overheated condition for an extended period can result in device burnout.
