The INA126U by B&B Smartworx is a precision micropower instrumentation amplifier designed for accurate and low-noise differential signal acquisition. Its two-op-amp design ensures excellent performance with a very low quiescent current of 175µA per channel.
This amplifier operates over a wide supply voltage range of ±1.35V to ±18V, making it ideal for portable instrumentation and data acquisition systems. The gain can be precisely set from 5V/V to 10000V/V using a single external resistor. Laser-trimmed input circuitry contributes to a low offset voltage of 250µV maximum and a low offset voltage drift of 3µV/°C maximum.
Available in 8-pin DIP, SO-8 surface mount, and MSOP-8 surface-mount packages, the INA126U is specified for the industrial temperature range of –40°C to +85°C. Its low noise (35nV/√Hz) and low input bias current (25nA max) further enhance its suitability for demanding applications.
Applications include industrial sensor amplification (bridge, RTD, thermocouple), physiological signal amplification (ECG, EEG, EMG), multi-channel data acquisition, and portable, battery-operated systems.
