Product details

Single-supply instrumentation amp for sensor front-ends

It operates from a single supply spanning 2.7 V to 7.5 V, drawing only 93 µA quiescent current, making it suitable for battery-powered and loop-powered transmitters. The rail-to-rail output stage maximizes dynamic range at low supply voltages. Typical applications include bridge sensors, thermocouple amplifiers, and medical instrumentation front-ends where common-mode rejection and low offset are needed.

Tape & Reel and Cut Tape options are available for prototype or production volumes.

Frequently asked questions

Can MAX4194ESA+T operate from a 3.3V single supply?

Yes, the 2.7 V minimum supply span allows reliable operation from a 3.3 V rail. The rail-to-rail output swings close to both supply rails, preserving dynamic range.

What is the typical bandwidth of MAX4194ESA+T?

The -3 dB bandwidth is 250 kHz, with a slew rate of 0.06 V/µs. This suits DC and low-frequency sensor signals up to tens of kHz.

What is the typical application of MAX4194ESA+T?

Typical applications include bridge sensor amplifiers, thermocouple conditioners, medical instrumentation front-ends, and any low-power precision signal chain requiring a single-supply instrumentation amp with rail-to-rail output.
