MAX4094ASD+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4094ASD+ is a quad operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply from 2.7V to 6V or split supplies of ±1.35V to ±3V. Each amplifier draws less than 130µA quiescent current, with a maximum of 185µA at 5V. The device offers a gain-bandwidth product of 500kHz, an input offset voltage of 30µV typical, and high voltage gain of 115dB. It maintains stability driving capacitive loads up to 2000pF and provides a common-mode rejection ratio of 90dB.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail operation at both input and output terminals
• Beyond-the-Rails inputs prevent phase reversal for overdriven signals
• Unity-gain stable when driving capacitive loads exceeding 2000pF
• Micropower consumption with less than 130µA per op amp

Instrumentation, Op Amps, Buffer Amps Applications

• Portable equipment
• Battery-powered instruments
• Data acquisition and control systems
• Low-voltage signal conditioning

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component matches the exact part number MAX4094ASD+. Confirm the package type is 14-pin SOIC as specified in the datasheet. Ensure the temperature range covers -40°C to +125°C. Check for lead-free compliance if required by your assembly process. Validate that the supplier provides authentic Maxim Integrated products.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption and wide dynamic range at low voltages. It is suitable for battery-operated devices where minimizing current draw is critical. The rail-to-rail input and output maximize signal swing in single-supply systems. Consider the 14-pin SOIC package for board space constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4094 is part of the MAX409x family, which includes the single-channel MAX4091 and dual-channel MAX4092. All variants share similar electrical characteristics, including micropower operation and rail-to-rail performance. The MAX4094 specifically integrates four amplifiers in a 14-pin package, offering higher channel density compared to its single and dual counterparts.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include MAX4091ASA (single) and MAX4092ASA (dual). Other Maxim integrated products may offer similar specifications but require verification of pin compatibility and electrical parameters.
