Product Summary
The INA122PA is a single supply, micropower instrumentation amplifier. The INA122PA 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 INA122PA can be operated with single power supplies from 2.2V to 36V and quiescent current is a mere 60mA. It can also be operated from dual supplies. By utilizing an input level-shift network of the INA122PA, input commonmode range extends to 0.1V below negative rail (single supply ground).
