MAX4075CAESA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4075CAESA is a dual-channel fixed-gain operational amplifier from the GainAmp family, manufactured by Analog Devices Inc./Maxim Integrated. 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 high-voltage fault protection capable of withstanding ±17V at either input without damage. It offers rail-to-rail outputs that can drive a 1kΩ load while maintaining excellent DC accuracy.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features rail-to-rail output capability suitable for driving low-impedance loads
• Optimized for space-critical designs with compact package options

Instrumentation, Op Amps, Buffer Amps Applications

• Portable battery-powered equipment
• Instruments, terminals, and bar-code readers
• Photodiode preamplifiers
• Low-side current-sense amplifiers

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 operating temperature range matches the application requirements, noting the standard -40°C to +70°C rating. Ensure the SOIC-8 package footprint aligns with existing board layouts. Cross-reference the datasheet for absolute maximum ratings to prevent overvoltage conditions during system integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed gain is sufficient, eliminating external resistor networks and reducing layout complexity. Ideal for applications requiring high input fault tolerance up to ±17V. Consider the trade-off between bandwidth and gain, as higher gains result in lower bandwidth. Verify capacitive load stability requirements, as the device is stable up to 100pF without isolation resistors.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4074–MAX4078 GainAmp family, which combines micropower op amps with laser-trimmed internal feedback resistors. Unlike open-loop variants like the MAX4076, the MAX4075 provides fixed gain configurations directly. It shares the same core architecture with the MAX4074 but differs in channel count, offering dual channels in an 8-pin package compared to the single-channel MAX4074.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional replacements within the same family include other MAX4075 variants with different gain codes or packages (e.g., MAX4075EUA). For open-loop alternatives, consider the MAX4076 series. Verify pin compatibility and thermal characteristics when substituting.
