INA2126UA Description

Short technical summary and product information.

The INA2126UA from Burr-Brown Corp is a precision dual micropower instrumentation amplifier ideal for portable instrumentation and data acquisition systems. It utilizes a two-op-amp design to achieve excellent performance with very low quiescent current of 175µA per channel.

Key electrical specifications include a wide operating supply voltage range of ±1.35V to ±18V, a low offset voltage of 250µV maximum, and low offset drift of 3µV/°C maximum. The amplifier provides low noise performance with 35nV/√Hz at 1kHz and a low input bias current of 25nA maximum. Gain can be set from 5V/V to 10000V/V using a single external resistor.

This instrumentation amplifier operates within an industrial temperature range of –40°C to +85°C. It is available in surface-mount packages such as SOIC, making it suitable for various electronic designs. The INA2126UA is well-suited for applications requiring accurate differential signal acquisition in power-sensitive environments.

Applications include industrial sensor amplification (Bridge, RTD, Thermocouple), physiological signal amplification (ECG, EEG, EMG), multi-channel data acquisition, and portable, battery-operated systems.
