MAX516AENG+

Overview

The MAX516AENG+ is a quad analog comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 24-pin PDIP-Narrow package. It features DAC-programmed threshold control for precise voltage comparison without external resistors. The device operates on a single supply voltage ranging from 4.75 V to 16.5 V with an operating supply current of 10 mA. Key electrical parameters include a propagation delay time of 0.8 µs and an input bias current of 400 nA. It supports CMOS and TTL output types and functions as a general-purpose comparator suitable for various linear applications.

Feature Summary

• DAC-programmed threshold control eliminates the need for external resistor networks
• Quad configuration integrates four independent comparators in a single package
• CMOS and TTL compatible output stages ensure broad interface flexibility
• General-purpose design optimized for standard linear circuit applications

Applications

• Precision voltage monitoring systems requiring programmable thresholds
• Industrial control circuits utilizing digital-to-analog threshold adjustment
• Battery management systems with defined voltage limit detection
• Signal processing interfaces requiring fast general-purpose comparison

Procurement Notes

Verify the specific suffix 'ENG+' to confirm the PDIP-24 narrow package variant, as other suffixes indicate different packages like SOIC or TSSOP. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the source is an authorized distributor to guarantee component authenticity and traceability. Check for any obsolescence notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when multiple independent comparators are required within a single footprint to save board space. Choose the MAX516AENG+ over discrete solutions if programmable thresholds via internal DACs are necessary to reduce external component count. Verify that the 4.75 V minimum supply voltage aligns with the system power rails. Consider the 0.8 µs propagation delay against application speed requirements to ensure adequate response times for signal processing tasks.

Part Context

The MAX516A series belongs to the linear comparators family from Maxim Integrated, now part of Analog Devices. This specific part represents the quad-channel variant designed for applications needing multiple comparison functions. The ENG+ designation specifically identifies the plastic dual-in-line package version, distinguishing it from surface-mount alternatives within the same functional family.

Replacement Considerations

Direct pin-compatible replacements may include other quad comparators with similar supply ranges, but verify DAC functionality availability. Cross-reference with MAX516 variants having different package suffixes if form factor changes are acceptable. Ensure replacement parts maintain comparable propagation delay and input bias current specifications for equivalent performance.
