The AD8422ARMZ is a high precision rail-to-rail Instrumentation Amplifier delivers the best performance per unit microampere in the industry. The AD8422 processes signals with ultralow distortion performance that is load independent over its full output range. The AD8422 is the third generation development of the industry-standard AD620. The AD8422 employs new process technologies and design techniques to achieve higher dynamic range and lower errors than its predecessors, while consuming less than one-third of the power. The AD8422 uses the high performance pin-out introduced by the AD8221. Very low bias current makes the AD8422 error-free with high source impedance, allowing multiple sensors to be multiplexed to the inputs. Low voltage noise and low current noise make the AD8422 an ideal choice for measuring a Wheatstone bridge. The wide input range and rail-to-rail output of the AD8422 bring all of the benefits of a high performance in-amp to single-supply applications.
