The Analog Devices MAX4042EUA+ is a dual general-purpose op-amp with rail-to-rail output, built for low-power signal conditioning in battery-powered or loop-powered systems. It draws 14 µA per channel, runs on a 2.4 V to 5.5 V supply span, and delivers 90 kHz gain-bandwidth product with a 0.04 V/µs slew rate — enough for DC and low-frequency sensor signals, thermocouple amplifiers, or battery-monitor front-ends.

Frequently asked questions
Is MAX4042EUA+ rail-to-rail?
Yes, the output type is rail-to-rail, allowing the output to swing close to both supply rails — useful for single-supply designs and ADC interfaces.
What is the bandwidth of MAX4042EUA+?
The gain-bandwidth product is 90 kHz, and the slew rate is 0.04 V/µs — suited for DC and low-frequency signal conditioning.
What is an equivalent part for MAX4042EUA+?
Within the same family, the single-channel MAX4040 and quad-channel MAX4044 share the same 90 kHz GBW, 14 µA supply, and rail-to-rail output — pinout differs by channel count, not footprint.
