The INA322 family is a series of low cost, rail-to-rail output, micropower CMOS instrumentation amplifiers that offer widerange, single-supply, as well as bipolar-supply operation. The INA322 family provides low-cost, low-noise amplification of differential signals with micropower current consumption of 40A. When shutdown the INA322 has a quiescent current of less than 1A. Returning to normal operations within microseconds, the shutdown feature makes the INA322 optimal for low-power battery or multiplexing applications.
