AD8638 - Operational Amplifiers

Description

The AD8638/AD8639 are single and dual wide bandwidth, auto-zero amplifiers featuring rail-to-rail output swing and low noise.

These amplifiers have very low offset, drift, and bias current.

Operation is fully specified from 5 V to 16 V single supply (±2.5 V to ±8 V dual supply).

Features

  • Low offset voltage: 9 μV maximum Offset drift: 0.04 μV/°C maximum Rail-to-rail output swing 5 V to 16 V single-supply or ±2.5 V to ±8 V dual-supply operation High gain: 136 dB typical High CMRR: 133 dB typical High PSRR: 143 dB typical Very low input bias current: 40 pA maximum Low supply current: 1.3 mA maximum AD8639: qualified for automotive.
