Product details

Single-supply instrumentation amp — 200 kHz bandwidth, 175 µA quiescent

It delivers a 200 kHz bandwidth with a 0.4 V/µs slew rate, drawing only 175 µA supply current — a combination that suits battery-powered sensor interfaces and portable medical devices.

DC precision — offset and bias current

These figures keep DC errors low in bridge-type sensors (strain gauges, pressure transducers) where the signal is a few millivolts.

Output drive and packaging

The 8-SOIC (0.154" width) footprint is a standard surface-mount package, compatible with common PCB layouts.

Frequently asked questions

Can INA126UAG4 operate from a single supply?

Yes, the INA126UAG4 is designed for single-supply operation across a 2.7 V to 36 V span, making it suitable for battery-powered and industrial single-rail systems.

What is the quiescent current of INA126UAG4?

The supply current is 175 µA typical, which keeps power dissipation low in portable and loop-powered designs.
