Introduction

AI Translation

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 60μA. 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). A single external resistor sets gain from 5V/V to 10000V/V. Laser trimming provides very low offset voltage (250μV max), offset voltage drift (3μV/°C max) and excellent common-mode rejection. Package options include 8-pin plastic DIP and SO-8 surface-mount packages. Both are specified for the -40°C to +85°C extended industrial temperature range.
