AD822ARMZ

产品概述

The AD822ARMZ 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.
