MAX494CPD+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX494CPD+ is a quad micropower operational amplifier featuring rail-to-rail input and output capabilities. It operates from a single supply of +2.7V to +6V or split supplies of ±1.35V to ±3V. Each amplifier draws less than 150µA quiescent current while maintaining a 500kHz gain-bandwidth product and unity-gain stability. The device offers high voltage gain, low offset voltage, and the ability to drive large capacitive loads without external compensation.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input common-mode voltage range extending beyond supply rails
• Rail-to-rail output swing capability for maximum dynamic range
• Micropower operation with low quiescent current per amplifier
• High open-loop gain and excellent common-mode rejection ratio

Instrumentation, Op Amps, Buffer Amps Applications

• Portable equipment requiring low power consumption
• Battery-powered instruments
• Data acquisition systems
• Signal conditioning circuits
• Low-voltage applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any updates to electrical characteristics. Ensure storage conditions meet specified humidity and temperature limits to maintain reliability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring simultaneous rail-to-rail input and output performance in low-voltage environments. Consider the quad configuration for space-constrained multi-channel applications. Evaluate thermal dissipation requirements based on load conditions and ambient temperature ranges.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX492/MAX494/MAX495 family of micropower, single-supply rail-to-rail op amps. The MAX494 specifically provides four amplifiers in a single package, offering a cost-effective solution for multi-channel signal processing tasks compared to using multiple dual or single amplifier packages.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The manufacturer indicates the MAX495 was manufactured by an outside foundry using an unavailable process. While the MAX494 shares the same family, verify compatibility if substituting. Industry second-sources may be available; confirm pinout and electrical specifications match before implementation.
