3 Description

The INA122 is a precision instrumentation

amplifier for accurate, low-noise differential signal

acquisition. The two-op-amp design provides

excellent performance with very low quiescent current

(60μA), and is designed for portable instrumentation

and data acquisition systems. The INA122 can be

operated with single or dual power supplies from 2.2V

to 36V.

A single external resistor sets gain from 5V/V to

10000V/V. Laser trimming provides very low offset

voltage (250μV maximum), offset voltage drift (3μV/°C

maximum) and excellent common-mode rejection.

Package options include 8-pin plastic DIP and

SOIC surface-mount packages. Both packages are

specified for the −40°C to +85°C temperature range.
