Product Overview

The AD8221ARZ is a High Performance Precision Instrumentation Amplifier that delivers the industry's highest CMRR over frequency in its class. The CMRR of instrumentation amplifiers on the market today falls off at 200Hz. In contrast, it maintains a minimum CMRR of 80dB to 10kHz for all grades at G=1. High CMRR over frequency allows AD8221 to reject wideband interference and line harmonics, greatly simplifying filter requirements. Possible applications include precision data acquisition, biomedical analysis and aerospace instrumentation. Low voltage offset, low offset drift, low gain drift, high gain accuracy and high CMRR make this part an excellent choice in applications that demand the best DC performance possible, such as bridge signal conditioning. Programmable gain affords the user design flexibility. A single resistor sets the gain from 1 to 1000. The AD8221 operates on both single and dual supplies and is well suited for applications where ±10V input voltages are encountered.
  • Easy to use
  • Gain set with 1 external resistor (gain range 1 to 1000)
  • Low noise
  • 25µV Maximum input offset voltage
  • 0.3µV/°C Maximum input offset drift
  • 0.4nA Maximum input bias current
