AD8422 - Precision Instrumentation Amplifier

Description

The AD8422 is a high precision, low power, low noise, rail-to-rail instrumentation amplifier that delivers the best performance per unit microampere in the industry.

The AD8422 processes signals with ultralow distortion performance that is load independent over its full output range.

Features

  • Low power: 368 µA maximum quiescent current.
  • Rail-to-rail output.
  • Low noise and distortion.
  • 8 nV/√Hz maximum input voltage noise at 1 kHz.
  • 0.15 µV p-p RTI noise (G = 100).
  • 0.5 ppm nonlinearity with 2 kΩ load (G = 1).
  • Excellent ac specifications.
  • 80 dB minimum CMRR at 10 kHz (G = 1).
  • 2.2 MHz bandwidth (G = 1).
  • High precision dc performance (AD8422BRZ).
  • 150 dB minimum CMRR (G = 1000).
  • 0.04% maximum gain error (G = 1000).
  • 0.3 µV/°C m.
