AD822 is a single-supply, rail-to-rail low power FET-input op amp with true single-supply operation, output swings, voltage range, load drive capability, low power, high AC performance, good DC performance, low noise and no phase inversion.
The AD822 is a dual precision, low‑power operational amplifier that can operate from a single supply of 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. It features rail‑to‑rail input and output, a unity‑gain bandwidth of 1.8 MHz, and can drive capacitive loads up to 350 pF while providing a minimum output current of 15 mA.
The device is offered in three 8‑lead packages (PDIP, SOIC, MSOP) and is suited for battery‑powered instrumentation, photodiode pre‑amps, active filters, 12‑ to 14‑bit data‑acquisition systems, medical instrumentation, and low‑power reference/regulator applications.
