Product Summary

The INA2126U is a precision instrumentation amplifier for accurate, low noise differential signal acquisition. Their two-op-amp design provides excellent performance with very low quiescent current (175μA/channel). This, combined with a wide operating voltage range of ±1.35V to ±18V, makes the INA2126U ideal for portable instrumentation and data acquisition systems. The applications of the INA2126U include industrial sensor amplifier: bridge, rtd, thermocouple, physiological amplifier: ecg, eeg, emg, multi-channel data acquisition and portable, battery operated systems.
