LMV7251M5

Overview

The LMV7251M5 is a general-purpose comparator manufactured by National Semiconductor, now part of Texas Instruments. It features rail-to-rail push-pull output and is designed for low-voltage operation starting at 1.8V. Key electrical specifications include a maximum offset voltage of 6000 µV and a typical response time of 670 ns. The device utilizes BICMOS technology and is housed in a PDSO5 package.

Feature Summary

• Rail-to-rail push-pull output capability
• Low voltage operation down to 1.8V
• General-purpose design with BICMOS technology

Applications

• Low voltage signal processing
• Battery-powered systems
• Threshold detection circuits

Procurement Notes

Verify the manufacturer status as National Semiconductor is acquired by Texas Instruments. Confirm the obsolete product status if sourcing new units. Ensure the PDSO5 package matches the required footprint. Check for equivalent current production parts from TI if availability is a constraint.

Selection Notes

Select this component for applications requiring rail-to-rail output swing in single-supply environments. Consider the 6000 µV max offset voltage for precision requirements. The 670 ns response time suits moderate-speed switching applications. Verify power supply constraints align with the 1.8V minimum operating voltage.

Part Context

This comparator belongs to the LMV725x series of low-voltage comparators. It shares functional similarities with other members like the LMV7219 but differs in specific performance metrics such as speed and internal hysteresis options. The M5 suffix indicates the specific package type used in this variant.

Replacement Considerations

Check for Texas Instruments equivalents such as the LMV7251NOPB or similar rail-to-rail comparators. Verify pin compatibility and electrical parameter overlaps before substitution.
