The INA122UA/2K5 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 INA122UA/2K5 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 common-mode 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.
Packages 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.
