AD8221TRMZ-EP-R7

AD8221TRMZ-EP-R7 is a precision instrumentation amplifier. It is a gain-programmable, high-performance instrumentation amplifier that delivers the industry’s highest CMRR over frequency in its class. In contrast, this device maintains a minimum CMRR of 80dB to 10KHz at G = 1. High CMRR over frequency allows the device 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 device an excellent choice in applications that demand the best DC performance possible, such as bridge signal conditioning. It is used in applications such as bridge amplifiers, precision data acquisition systems, strain gages, and transducer interfaces.
