ADI AD820ANZ

J-FETRail-to-Rail1,8 МГц

Overview

The AD820ANZ is a Rail-to-rail FET Input Operational Amplifier that can operate from a single supply of 5 to 36V or dual supplies of ±2.5 to ±18V. It has true single-supply capability with an input voltage range extending below the negative rail, allowing the AD820ANZ to accommodate input signals below ground 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, typical input bias currents below 25pA and low input voltage noise provide DC precision with source impedances up to 1GR. 1.8MHz unity gain bandwidth, -93dB THD at 10kHz and 3V/µs slew rate are provided for a low supply current of 800µA. The op amp drives up to 350pF of direct capacitive load and provides a minimum output current of 15mA. This allows the amplifier to handle a wide range of load conditions.
