LMV7239M7

Overview

The LMV7239M7 is a single-channel analog comparator from Texas Instruments, housed in a 5-pin SC-70 package. It features rail-to-rail input capability and offers both open-drain and push-pull output configurations. The device operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 62 ns, a typical power supply current of 95 µA at 5 V, and a maximum input offset voltage of 6 mV. The input bias current is specified at 0.4 µA, with common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) values of 67 dB and 85 dB, respectively.

Feature Summary

• Rail-to-rail input stage allows for full common-mode voltage range extension beyond the supply rails.
• Dual output configuration provides flexibility with both open-drain and push-pull options.
• Ultra-low power consumption suitable for battery-operated applications.
• Compact SC-70 packaging designed for space-constrained systems.

Applications

• General-purpose signal comparison in low-voltage circuits
• Threshold detection in portable electronic devices
• Voltage monitoring in battery-powered systems

Procurement Notes

Verify the specific suffix M7 against the manufacturer's latest documentation to confirm package type and availability status. Ensure that the component meets all required environmental standards for the intended application. Cross-reference ordering information with authorized distributors to confirm current production lifecycle status and lead times.

Selection Notes

Select this component when a single comparator with rail-to-rail inputs is required in a minimal footprint. The choice between open-drain and push-pull outputs should be based on system interface requirements. Consider the 62 ns propagation delay and 95 µA current consumption relative to performance needs. Verify compatibility with the target supply voltage range of 2.7 V to 5.5 V.

Part Context

The LMV7239M7 belongs to the LMV7239 family of ultra-low power comparators. This series is characterized by its ability to operate with low supply voltages while maintaining fast response times. The family includes variants with different output types and packages, such as SOT-23 and SC-70, catering to diverse design constraints in consumer and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as LMV7239M5/NOPB or LMV7239QDBVRQ1, ensuring functional equivalence in output type and electrical parameters. Verify package dimensions and thermal characteristics if substituting with other manufacturers' parts.
