Product details

Precision bridge amplifier for industrial sensing

The INA125U: Its 50 µV input offset voltage and 10 nA input bias current let it resolve microvolt-level signals from strain gauges, bridge sensors, and thermocouple outputs without the offset drift you'd get from a general-purpose op-amp.

Bandwidth and slew — signal conditioning, not fast acquisition

The 150 kHz bandwidth and 0.2 V/µs slew rate tell you this is a DC-to-low-frequency part. It is sized for precision bridge excitation and readout, thermocouple amplifiers, and industrial process-control loops — not for audio or high-speed data conversion front ends. The 460 µA supply current keeps it friendly for loop-powered transmitters.

Package and rework — 16-SOIC, no surprises

It reflows cleanly with a standard profile; no exposed pad to worry about. Tube shipment means the parts arrive with leads protected, but they come out of the tube with a static-dissipative handling step.

Frequently asked questions

What is the INA125U used for?

It is a precision instrumentation amplifier used for bridge sensor readout, strain gauge amplification, thermocouple conditioning, and industrial process-control signal chains where low offset and low drift matter.
