Dual zero-drift op-amp for precision DC measurement chains
The Analog Devices MAX44248AUA+ is a dual zero-drift operational amplifier with 2 µV typical input offset. Rail-to-rail output swings and a 2.7 V to 36 V supply span allow direct ADC interface and industrial bus use. Each channel draws 90 µA supply current.
What the 2 µV offset and 0.7 V/µs slew rate mean for your design
The 2 µV input offset voltage is the headline number for this part — it eliminates the need for a trim pot or digital calibration in most bridge-amplifier and thermocouple-front-end circuits. The zero-drift architecture keeps that offset stable across the -40°C to 125°C industrial range, so the system gain error stays within the ADC's LSB budget without a periodic re-zero cycle. The 0.7 V/µs slew rate and 1 MHz gain-bandwidth product are modest — this is not a part for high-speed ADC drivers or video buffers. It is sized for DC and low-frequency AC signals: strain gauges, load cells, RTD inputs, and current-shunt amplifiers where the signal bandwidth stays under a few kilohertz.
Package and footprint — 8-uMAX/uSOP
The MAX44248AUA+ comes in an 8-pin uMAX/uSOP package (3.00 mm body width), which is the same footprint as a standard MSOP-8. The supplier device package is listed as 8-uMAX/uSOP. It ships in Tube form.
Lifecycle and sourcing
The MAX44248AUA+ carries an Active lifecycle status with ROHS3 compliance. For BOM qualification into a production design, this part does not carry a near-term end-of-life risk.
