Single-supply instrumentation amp for sensor front-ends
The Maxim Integrated MAX4194ESA+T is a single-channel instrumentation amplifier in an 8-SOIC package, designed for precision sensor signal conditioning where low power and rail-to-rail output swing are required. 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.
Industrial temperature grade and package
Rated for -40°C to 85°C, this part fits industrial environments: motor drives, outdoor telecom cabinets, factory automation panels, and under-hood automotive (non-AEC-Q100). The 8-SOIC package is a standard footprint for board-level assembly, compatible with most pick-and-place lines. Tape & Reel and Cut Tape options are available for prototype or production volumes.
Lifecycle and sourcing
The MAX4194ESA+T carries an Active lifecycle status with ROHS3 compliance. No end-of-life notice is in effect, so it remains a safe choice for new designs and production BOMs.
