MAX516BENG

Overview

The MAX516BENG is a quad general-purpose analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It features DAC-programmable thresholds and CMOS/TTL outputs. The device operates on a single supply voltage ranging from 4.75 V to 16.5 V, with a typical operating current of 10 mA. Key electrical specifications include an input bias current of 400 nA and a response time of 800 ns. It is housed in a 24-pin PDIP package and supports an extended industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent comparators within a single compact package for space-constrained designs.
• Features digitally programmable threshold voltages via internal DACs, eliminating the need for external resistor networks.
• Provides flexible output compatibility with both CMOS and TTL logic families.

Applications

• Threshold detection circuits requiring precise voltage monitoring
• Window comparator configurations for signal validation
• Over-voltage and under-voltage protection systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'E' indicates the extended temperature grade (-40°C to +85°C) and PDIP-24 packaging. Request official datasheets and certification documents to ensure compliance with project specifications before finalizing acquisition.

Selection Notes

Select this component when multiple independent comparison functions are required without external threshold setting components. Ensure the system power supply remains within the 4.75 V to 16.5 V operational range. Verify that the 800 ns propagation delay meets the timing requirements of the target application interface.

Part Context

This part belongs to the MAX516 series of quad comparators designed for general-purpose applications. It serves as a solution for integrating multiple comparison stages into a single footprint, reducing board space compared to discrete solutions. The series is characterized by its ability to program thresholds internally, simplifying circuit design and calibration processes.

Replacement Considerations

Cross-reference with other MAX516 variants such as MAX516ACNG+ or MAX516BCWG+ for pin-compatible alternatives. Verify that substitute parts match the required temperature range and package type before integration into existing hardware designs.
