LMV7271MFX/NOPB

Overview

The LMV7271MFX/NOPB is a single-channel analog comparator from Texas Instruments, characterized by rail-to-rail input and push-pull output capabilities. It operates within a supply voltage range of 1.8 V to 5.5 V, consuming a typical supply current of 9 µA per channel. The device features a propagation delay of 800 ns and an input offset voltage of 4 mV. It supports a maximum output current of 34 mA and offers a common-mode rejection ratio of 46 dB. The component is housed in a compact SC-70-5 package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail input stage enables operation with signals extending to the supply rails.
• Push-pull output stage provides active drive capability for low power consumption when driving loads.
• Low power consumption design allows operation at supply voltages as low as 1.8 V.

Applications

• Level-shifting applications where output can be pulled to any voltage up to 5.5 V
• Low voltage and low power circuit designs
• Space-critical PCB layouts requiring small package footprints

Procurement Notes

Verify the specific suffix 'MFX' corresponds to the SC-70-5 tape-and-reel packaging configuration. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance status. Ensure the ordering part number matches the required package type and reel quantity specifications provided by the manufacturer or authorized distributors.

Selection Notes

Select this component for applications requiring a balance between low power consumption and moderate speed. The push-pull output is suitable for direct interfacing with digital logic without external pull-up resistors. Consider the 4 mV input offset voltage for precision requirements and verify that the 800 ns propagation delay meets the system timing constraints.

Part Context

This device belongs to the LMV727x family of rail-to-rail input low power comparators built on submicron silicon-gate BiCMOS process technology. The family includes single-channel variants like the LMV7271 and dual-channel options, designed to reduce PCB area through tiny packages while maintaining bipolar input noise performance and CMOS output swing characteristics.

Replacement Considerations

The LMV7271MGX/NOPB is a verified substitute offering identical electrical specifications but packaged in an SC-70-5 form factor instead of SOT-23-5. Verify pinout compatibility and physical footprint dimensions before substitution.
