The Maxim Integrated MAX4037EUT+T is a single general-purpose op-amp in a SOT-23-6 package, designed for low-frequency signal conditioning where supply current is the critical budget line. Its 4 kHz gain-bandwidth product and 0.004 V/µs slew rate place it firmly in the micropower category — think battery-monitor front-ends, thermocouple cold-junction compensation, or always-on comparator-replacement loops where the amplifier idles at 2 µA supply current. Rail-to-rail output swing at 13 mA per channel lets it drive a low-power ADC reference or a small-signal MOSFET gate without a second buffer stage.
