MAX4075AOESA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4075AOESA+T is a dual-channel, fixed-gain operational amplifier from the GainAmp family. It operates on a single +2.5V to +5.5V supply with a typical supply current of 34µA per amplifier. The device features factory-trimmed internal gain-setting resistors providing 0.1% gain accuracy and offers standard noninverting gains ranging from +1.25V/V to +101V/V. It includes high-voltage fault protection capable of withstanding ±17V at either input without damage. The output swings rail-to-rail and can drive a 1kΩ load while maintaining excellent DC accuracy.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific gain code suffix required for the desired voltage gain configuration, as the base part number requires this addition. Confirm the package type matches the design requirements, as the SOIC-8 variant is specified for this model. Ensure the operating temperature range aligns with the -40°C to +70°C specification provided in the datasheet.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed-gain solution is preferred over discrete resistor networks to minimize board space and cost. The device is suitable for applications requiring low power consumption and high input fault tolerance. Consider the available gain options in the Gain Selector Guide to ensure the specific gain meets the system bandwidth and accuracy requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the Maxim Integrated GainAmp family, which combines low-cost rail-to-rail op amps with precision internal gain-setting resistors. The family includes open-loop unity-gain-stable versions (MAX4076/77/78) and fixed-gain versions (MAX4074/75). The MAX4075 specifically provides dual-channel fixed-gain functionality in an 8-pin SOIC or µMAX package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4074 serves as the single-channel equivalent within the same family. Other GainAmp variants such as the MAX4076, MAX4077, and MAX4078 offer open-loop configurations but lack the integrated gain-setting resistors.
