AD8222 - Dual-Channel Instrumentation Amplifier

Datasheet Summary

Description

The AD8222 is a dual-channel, high performance instrumentation amplifier that requires only one external resistor per amplifier to set gains of 1 to 10,000.

Features

  • Two channels in small 4 mm × 4 mm LFCSP Gain set with 1 resistor per amplifier (G = 1 to 10,000) Low noise 8 nV/√Hz at 1 kHz 0.25 µV p-p (0.1 Hz to 10 Hz) High accuracy dc performance (B grade) 60 µV maximum input offset voltage 0.3 µV/°C maximum input offset drift 1.0 nA maximum input bias current 126 dB minimum CMRR (G = 100) Excellent ac performance 140 kHz bandwidth (G = 100) 13 µs settling time to 0.001% Differential output option (single channel) Fully specified Adjustable common-mode outp.
