The INA322 family provides low-cost, low-noise amplification of differential signals with micropower current consumption of 40µA. When shutdown the INA322 has a quiescent current of less than 1µA. Returning to normal operations within microseconds, the shutdown feature makes the INA322 optimal for low-power battery or multiplexing applications. R1 Configured internally for 5V/V gain, the INA322 offers exceptional flexibility with user-programmable external gain resistors. The INA322 reduces common-...
