MAX4075ADESA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4075ADESA+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, driving 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 this determines the functional performance. Confirm that the SOIC-8 package matches the target board layout. Ensure the operating temperature range aligns with system requirements. Cross-reference the ordering information to validate the exact part number against the manufacturer's latest documentation before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed-gain solution reduces external resistor count and board space. It is suitable for applications requiring high-voltage tolerance at the input pins. Consider the available gain options in the Gain Selector Guide to match the signal conditioning needs. Verify that the capacitive load does not exceed stability limits without an isolation resistor.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the Maxim Integrated GainAmp family, which combines low-cost op amps with laser-trimmed internal resistors. The MAX4075 specifically provides dual channels, whereas the MAX4074 is the single-channel variant. These devices are designed to replace discrete op amp and resistor networks, offering plug-in compatibility with existing designs.
