AD8293G160 - Zero-Drift In-Amp

Download the AD8293G160 datasheet PDF. This datasheet also covers the AD8293G80 variant, as both devices belong to the same zero-drift in-amp family and are provided as variant models within a single manufacturer datasheet.

General Description

The AD8293G80/AD8293G160 are small, low cost, precision instrumentation amplifiers that have low noise and rail-to-rail outputs.

They are available in two fixed-gain models: 80 and 160.

They incorporate the gain setting resistors and filter resistors, reducing the number of ancillary components.

Key Features

  • Small package: 8-lead SOT-23 Reduced component count Incorporates gain resistors and filter resistors Low offset voltage: 20 μV maximum Low offset drift: 0.3 μV/°C maximum Low gain drift: 25 ppm/°C maximum High CMR: 140 dB typical Low noise: 0.7 μV p-p from 0.01 Hz to 10 Hz Single-supply operation: 1.8 V to 5.5 V Rail-to-rail output Available in 2 fixed-gain models.
