LMV7219M5X

Overview

The LMV7219M5X/NOPB is a single-channel analog comparator manufactured by Texas Instruments, designed for high-speed applications within a 2.7V to 5V supply range. It features a rail-to-rail output stage and a push-pull configuration, enabling full signal swing across the supply rails. The device utilizes BiCMOS process technology to achieve a typical propagation delay of 20ns and a response time of 7ns. Key electrical specifications include a maximum input offset voltage of 6mV at 5V, a typical common-mode rejection ratio (CMRR) of 85dB, and a power supply rejection ratio (PSRR) of 85dB. It operates with a maximum static current of 1.8mA and supports an operating temperature range from -40°C to +85°C in a compact SOT-23-5 surface-mount package.

Feature Summary

• Rail-to-rail output capability ensures maximum dynamic range in low-voltage systems
• High-speed performance with 7ns response time suitable for fast signal processing
• Low power consumption with 1.8mA maximum supply current
• Push-pull output structure provides strong drive capability

Applications

• Battery-powered portable electronics requiring low voltage operation
• Threshold detection circuits in industrial control systems
• Signal conditioning stages in communication equipment
• Over-voltage and under-voltage protection monitoring

Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as some records indicate non-compliance or SVHC presence. Ensure the ordering part number includes '/NOPB' for lead-free manufacturing standards. Cross-reference distributor datasheets for exact shipping quantities and moisture sensitivity levels before finalizing procurement orders.

Selection Notes

Select this component when a single comparator with rail-to-rail output is required in a small SOT-23-5 footprint. It is appropriate for designs needing fast propagation delays under 20ns with minimal power draw. Consider the 6mV max input offset voltage for precision requirements. Verify that the 2.7V minimum supply voltage aligns with the system's available power rails.

Part Context

This part belongs to the LMV7219 family of high-speed comparators from Texas Instruments. It serves as a general-purpose analog comparator alternative to operational amplifiers in switching applications. The device is pin-compatible with other SOT-23-5 comparators but offers distinct speed and output characteristics tailored for low-voltage digital interfacing.

Replacement Considerations

LMV7219M5/NOPB is the non-reel variant of the same functional device.
