Key numbers for the bench: 0.4 V/µs slew rate and 200 kHz -3 dB bandwidth. That is enough for low-frequency sensor outputs — strain gauges, RTDs, ECG leads — but it will roll off a 10 kHz square wave noticeably. The 175 µA supply current makes it a candidate for battery-powered or loop-powered designs. Supply span runs from 2.7 V up to 36 V, single or dual rail. Input offset voltage is 150 µV typical, input bias current 10 nA. Output can source or sink 10 mA per channel. You can swap it on site with a basic hot-air station or even a fine-tipped iron if the board has enough pad access.","metaTitle":"INA126UA Instrumentation Amplifier, 0.4V/µs Slew Rate","metaDescription":"Texas Instruments INA126UA single instrumentation amplifier. 0.4V/µs slew rate, 200 kHz bandwidth, 175 µA supply.

The INA126UA draws 175 µA versus the INA128's 700 µA, making it the lower-power choice for battery-operated sensor interfaces.
