MAX4282EUA+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4282EUA+ is a dual-channel, open-loop, unity-gain stable operational amplifier from the GainAmp family. It operates on a single +2.5V to +5.5V supply with a typical supply current of 320µA per amplifier. The device features rail-to-rail outputs capable of driving a 1kΩ load and maintains excellent DC accuracy. Input fault protection withstands ±17V at either input without excessive current draw. The gain bandwidth product is 2MHz, and it remains stable with capacitive loads up to 470pF.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type against the datasheet, as the source material lists SOT23-5 for the MAX4282 series but the model suffix suggests µMAX. Confirm availability status directly with the manufacturer or authorized distributors, as stock levels fluctuate. Ensure the operating temperature range matches the application requirements before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel, unity-gain stable op amp is required within the GainAmp ecosystem. It serves as an ideal replacement for discrete resistor networks in fixed-gain applications where layout space is limited. Consider its low supply current and wide input voltage range for battery-powered designs requiring robust fault tolerance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the Maxim Integrated GainAmp family, which integrates precision internal gain-setting resistors or open-loop cores into ultra-small packages. The MAX4282 specifically provides the dual-channel variant of the open-loop, unity-gain stable core used across the MAX4281/4282/4284 series.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4281 (single channel) and MAX4284 (quad channel) are confirmed substitutes within the same family offering identical electrical characteristics and pinouts.
