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. The rail-to-rail output swings within millivolts of the supply rails, maximizing ADC dynamic range on a 2.85 V to 5.5 V supply. The -40°C to 125°C temperature range covers industrial and automotive under-hood environments, and the 8-uMAX/uSOP package fits tight mixed-signal layouts.
Active production, no LTB watch needed
The MAX4209HAUA+ carries an active lifecycle status and ROHS3 compliance. No end-of-life notice or last-time-buy window is documented.
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.
