MAX4958ETB+

Overview

The MAX4958ETB+ is not a valid component within the provided documentation. The source material exclusively details the MAX492, MAX494, and MAX495 operational amplifiers. These devices are single/dual/quad micropower, single-supply rail-to-rail op amps. They operate from +2.7V to +6V single supplies or ±1.35V to ±3V split supplies. Key electrical parameters include a 500kHz gain-bandwidth product, 150µA max quiescent current per amplifier, and 25nV/√Hz input noise voltage density.

Feature Summary

• Rail-to-rail input common-mode voltage range extending beyond supply rails without phase reversal
• Rail-to-rail output swing capability for increased dynamic range in low-voltage applications
• Micropower operation with less than 150µA supply current per amplifier
• High DC accuracy with low offset voltage and high open-loop gain

Applications

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

Procurement Notes

Verify the exact part number before procurement as the MAX4958ETB+ does not appear in the provided datasheet. The document confirms the MAX495 is Not Recommended for New Designs due to manufacturing process discontinuation. Ensure compatibility with existing designs if sourcing this obsolete component, or consult technical support for replacement options.

Selection Notes

Select the MAX495 when a single-channel, micropower, rail-to-rail operational amplifier is required for battery-operated or low-voltage systems. Consider the MAX492 for dual-channel or MAX494 for quad-channel configurations if multiple amplifiers are needed. Verify that the 500kHz bandwidth and 150µA current consumption meet system requirements.

Part Context

The MAX495 belongs to the MAX492/MAX494/MAX495 family of precision operational amplifiers manufactured by Maxim Integrated (now Analog Devices). It is specifically designed as the single-channel variant within this series, offering rail-to-rail input and output capabilities. The device is notable for its ability to drive large capacitive loads while maintaining stability, making it suitable for interfacing with analog-to-digital converters.

Replacement Considerations

The MAX495 is explicitly marked as Not Recommended for New Designs. Users should seek alternative components from Maxim Integrated or industry second-sources. Consult technical support for specific replacement recommendations compatible with existing PCB layouts and performance specifications.
