Product details

90 kHz GBW at 14 µA — micropower rail-to-rail op-amp

The MAX4040ESA+ is a single-supply, rail-to-rail output op-amp from Analog Devices that draws only 14 µA supply current while delivering 90 kHz gain-bandwidth product. This combination suits battery-operated sensor interfaces, portable instrumentation, and always-on signal chains where every microamp counts. Supply voltage range spans 2.4 V to 5.5 V, covering single Li-ion, 3.3 V, and 5 V rails without a separate regulator.

Listed as Active by Analog Devices with ROHS3 compliance.
