MAX4078EUD

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4078EUD is a quad, 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 40µA per amplifier. Key electrical parameters include a gain-bandwidth product of 230kHz, a slew rate of 90V/ms, and an input offset voltage of up to 3.5mV. The device features rail-to-rail outputs capable of driving a 1kΩ load and maintains stability with capacitive loads up to 100pF.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure the component matches the required quad configuration and open-loop specifications. Cross-reference the manufacturer's latest datasheet for any updates regarding availability or pinout configurations before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-power, quad operational amplifier with rail-to-rail output is required. It is suitable for applications needing unity-gain stability and operation from a single low-voltage supply. Consider its 230kHz bandwidth and 40µA supply current for space-constrained, battery-operated designs where external feedback resistors are undesirable.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4074–MAX4078 GainAmp™ op amp family by Analog Devices / Maxim Integrated. While other members in the series feature fixed internal gain-setting resistors, the MAX4078 variant provides an open-loop, unity-gain-stable configuration. This distinction allows it to function as a standard general-purpose amplifier within the same low-power, rail-to-rail ecosystem.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements within the family include the MAX4076 (single) and MAX4077 (dual). Verify that the application requires the quad channel count and open-loop topology rather than the fixed-gain characteristics found in the MAX4074 or MAX4075 variants.
