AD8221 Precision Instrumentation Amplifier

Analog Devices AD8221 Precision Instrumentation Amplifier is a gain-programmable, high-performance instrumentation amplifier that delivers a high Common-Mode Rejection Ratio (CMRR) over frequency. The CMRR of instrumentation amplifiers on the market today falls off at 200Hz. In contrast, the AD8221 maintains a minimum CMRR of 80dB to 10kHz for all grades at G = 1. The high CMRR over frequency allows the AD8221 to reject wideband interference and line harmonics, greatly simplifying filter requirements. Possible applications include precision data acquisition, biomedical analysis, and aerospace instrumentation.
