Product Summary
The INA2331AIPWRG4 is a rail-to-rail output, low-power CMOS instrumentation amplifier that offers wide range, singlesupply operation as well as bipolar-supply operation. The INA2331AIPWRG4 provides low-cost, low-noise amplification of differential signals with a low quiescent current of 415μA (dropping to 0.01μA when shutdown). Returning to normal operation within microseconds, this INA can be used for battery or multi-channel applications. The applications of the INA2331AIPWRG4 include industrial sensor amplifiers: Bridge, RTD, Thermocouple, Position, physiological amplifiers: ECG, EEG, EMG, A/D converter signal conditioning, differential line receivers with gain, field utility meters, pcmcia cards, audio amplifiers, communication systems, test equipment and automotive instrumentation.
