Product Summary
The AD8221ARZ is a gain programmable, high performance instrumentation amplifier that delivers the highest CMRR over frequency in its class. The CMRR of instrumentation amplifiers on the market today falls off at 200 Hz. In contrast, the AD8221ARZ maintains a minimum CMRR of 80 dB to 10 kHz for all grades at G = 1. High CMRR over frequency allows the AD8221ARZ to reject wideband interference and line harmonics, greatly simplifying filter requirements. Possible applications include precision data acquisition, biomedical analysis, and aerospace instrumentation. The applications of the AD8221ARZ include Weigh scales, Industrial process controls, Bridge amplifiers, Precision data acquisition systems, Medical instrumentation, Strain gages and Transducer interfaces.
