AD8221ARMZ-RL

AD8221ARMZ-RL is a gain programmable, high performance instrumentation amplifier that delivers the industry’s highest CMRR over frequency in its class. The CMRR of instrumentation amplifier on the market today falls off at 200Hz. In contrast, this device maintains a minimum CMRR of 80dB to 10KHz for all grades 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 part an excellent choice in applications that demand the best dc performance possible, such as bridge signal conditioning It is used in applications such as weigh scales, industrial process controls, bridge amplifiers, precision data acquisition systems, medical instrumentation, strain gages, transducer interfaces.
