TIINA132UA/2K5
Overview
The INA132UA/2K5 is a low-power, precision differential amplifier consisting of an internal op amp and a precision resistor network. It is designed to convert differential signals to single-ended signals with a fixed gain of 1, offering excellent common-mode rejection and very low offset voltage. Operating over a wide supply range from 2.7V to 36V, it is optimized for battery-powered and industrial instrumentation applications.
Why Choose This Part
This device features an extremely low input offset voltage of 75 uV and a high common-mode rejection ratio, ensuring signal integrity in noisy environments. The integrated laser-trimmed resistors provide 0.1 percent gain accuracy and superior temperature stability compared to discrete solutions. Its low quiescent current of 175 uA makes it highly efficient for low-power and remote sensing applications.
Applications
Key Specifications
Getting Started
To implement the INA132, connect the differential input signal to pins 2 and 3, and ensure the reference pin 1 is connected to a low-impedance ground or reference voltage. Since the resistors are internal, no external gain-setting components are required, which simplifies PCB layout and improves precision. Decouple the power supply pins with 0.1uF ceramic capacitors located as close to the 8-SOIC package as possible.
