INA122UA (TEXAS INSTRUMENTS)

The INA122UA 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 single supply Micropower INA122 amplifier can be operated with single power supplies from 2.2 to 36V and quiescent current is a mere 60µA. It can also be operated from dual supplies. By utilizing an input level-shift network, input common mode range extends to 0.1V below negative rail (single supply ground). A single external resistor sets gain from 5 to 10000V/V. Laser trimming provides very low offset voltage (250µV maximum), offset voltage drift (3µV/°C maximum) and excellent common-mode rejection.
