LMV7251M7X

Overview

The LMV7251M7X is a single general-purpose comparator manufactured by National Semiconductor, now part of Texas Instruments. It operates on a single supply voltage ranging from 1.8V to 5V. The device features rail-to-rail input capability and a push-pull output stage. Key electrical specifications include a maximum input offset voltage of 6mV at 5V and a maximum input bias current of 0.016pA at 5V. It is housed in a compact SC-70-5 surface-mount package and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Rail-to-rail input capability allows operation with input signals extending to the supply rails.
• Push-pull output stage provides defined logic levels without requiring external pull-up resistors.
• Low voltage operation supports systems powered by supplies as low as 1.8V.

Applications

• Battery-powered portable electronics requiring low supply voltage operation
• Threshold detection circuits in consumer devices
• Signal conditioning for microcontroller input interfaces

Procurement Notes

Verify the manufacturer designation, as National Semiconductor was acquired by Texas Instruments. Ensure the ordering suffix matches the required package type (SC-70-5) and temperature grade. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the datasheet version to ensure alignment with current technical specifications.

Selection Notes

Select this component when a low-voltage, single-supply comparator with rail-to-rail inputs is required. The push-pull output simplifies interface design compared to open-collector alternatives. Consider the 6mV max input offset voltage for precision applications. The SC-70-5 package is suitable for space-constrained printed circuit board layouts.

Part Context

This part belongs to the LMV725x family of low-voltage comparators. The 'M7' suffix typically denotes the SC-70-5 package variant. Similar parts in the series may offer different configurations or performance characteristics. The family is designed for applications where power consumption and supply voltage are critical constraints.

Replacement Considerations

Direct substitutes within the same family include other LMV725x variants with compatible pinouts. Verify that any replacement maintains the SC-70-5 package and 1.8V to 5V operating range. Check for equivalent input offset voltage and bias current specifications to ensure circuit compatibility.
