Overview

The INA826AIDRGT is a low-power, precision instrumentation amplifier designed to operate over a wide supply range from 2.7 V to 36 V. It features a rail-to-rail output and is optimized for providing high common-mode rejection even at high frequencies. This component is specifically designed for signal conditioning in bridge-based sensors and medical instrumentation where power efficiency and input protection are critical.

Why Choose This Part

The device provides robust input protection up to +/-40 V beyond the supply rails, preventing damage during overvoltage events. With a low quiescent current of 200 uA and a wide operating temperature range from -40 C to 125 C, it is highly suitable for portable and thermally constrained industrial designs.

Applications

Industrial Process Control
Ideal for analog input modules and flow transmitters that require precise amplification of small differential signals in noisy environments.
Medical Instrumentation
Suitable for electrocardiogram (ECG) and surgical equipment due to its low noise and high accuracy.
Battery and LCD Testing
Used in test equipment to monitor small voltage drops across shunts or sensing elements with high precision.
Bridge Sensor Signal Conditioning
Excels at amplifying signals from force, humidity, and pressure sensors in industrial analytics.
