The INA122 is a precision instrumentation amplifier for accurate, low noise differential signal acquisition. Its two-op-amp design provides excellent performance with very low quiescent current, and is ideal for portable instrumentation and data acquisition systems. The INA122 can be operated with single power supplies from 2.2V to 36V and quiescent current is a mere 60A. It can also be operated from dual supplies. By utilizing an input level-shift network, input commonmode range extends to 0.1V below negative rail (single supply ground).
