Texas Instruments INA132 Low Power, Single-Supply Difference Amplifier INA132UG4

The INA132 is a low-power, single-supply difference amplifier designed for precision applications. It operates on a wide supply range, accommodating single supplies from 2.7V to 36V and dual supplies from ±1.35V to ±18V. The device features low gain error of ±0.075% and low nonlinearity of 0.001%, ensuring high accuracy in signal processing. Its typical common-mode rejection ratio is 90dB, making it suitable for environments with varying signal conditions. The INA132 integrates a precision op amp with a laser-trimmed resistor network, which enhances gain accuracy and common-mode rejection over temperature variations. It is particularly advantageous for single-supply applications due to its extended common-mode range down to the negative supply. The amplifier is housed in an SO-8 surface-mount package and is rated for operation over an industrial temperature range of -40°C to +85°C. Applications include optical modules, building security gateways, and various instrumentation tasks.
