INA322EA Datasheet

Micropower, Single-Supply, Cmos Instrumentation Amplifier


The INA322EA family is a series of low cost, rail-to-rail output, micropower CMOS instrumentation amplifiers that offer wide-range, 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 40&micro;A. When shutdown the INA322 has a quiescent current of less than 1&micro;A. Returning to normal operations within microseconds, the shutdown feature makes the INA322 optimal for low-power battery or multiplexing applications INA322EA Features &bull; Low Cost&bull; Low Quiescent Current: 40&micro;A/Channel Shut Down: < 1&micro;A&bull; High Gain Accuracy: G = 5, 0.07%, 2PPM/&deg;C&bull; Gain Set With External Resistors&bull; Low Bias Current: 10PA&bull; Bandwidth: 500KHZ, G = 5V/V&bull; Rail-To-Rail Output Swing: (V+) &ndash; 0.02V&bull; Wide Temperature Range: &ndash;55&deg;C to +125&deg;C&bull; Single Version In Msop-8 Package And Dual Version In Tssop-14 Package INA322EA Applications &bull; Industrial Sensor Amplifiers: Bridge, Rtd, Thermistor, Position&bull; Physiological Amplifiers: Ecg, Eeg, Emg&bull; A/D Converter Signal Conditioning&bull; Differential Line Receivers With Gain&bull; Field Utility Meters&bull; Pcmcia Cards&bull; Communication Systems&bull; Test Equipment&bull; Automotive Instrumentation
