Product details

Precision instrumentation amp for bridge and thermocouple front-ends

The MAX4209HAUA+ is a single-supply instrumentation amplifier from Analog Devices, built for precision low-frequency measurement. Its 3 µV input offset voltage and 1 pA input bias current let it interface directly with strain-gauge bridges, thermocouples, and other high-impedance sensors without an external buffer stage.

Active production, no LTB watch needed

Package and pinout — 8-uMAX/uSOP

The part ships in a Tube, 8-lead uMAX/uSOP package (3.00 mm body width, 0.118" pitch). Surface-mount only.

Frequently asked questions

What is the gain bandwidth product of MAX4209HAUA+?

The gain-bandwidth product is 750 kHz, with a -3 dB bandwidth of 7.5 kHz. This supports gains up to 100 for low-frequency precision measurements.

Is MAX4209HAUA+ equivalent to INA333?

Both are single-supply instrumentation amplifiers in similar packages, but the MAX4209HAUA+ has a 3 µV offset versus the INA333's 25 µV typical. Pin compatibility depends on the specific reference and gain-set architecture — verify the pinout against your layout before substituting.

What is the pinout of MAX4209HAUA+?

The MAX4209HAUA+ uses the standard 8-pin uMAX/uSOP instrumentation amplifier pinout. The exact pin functions are detailed in the datasheet; the reference pin sets the output common-mode level for single-supply designs.
