LMV7275MF

Overview

The LMV7275MF is a single-channel analog comparator from Texas Instruments, housed in an SC-70 (SOT-353) surface-mount package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V. The device features rail-to-rail input capability and an open-drain output stage. Key electrical parameters include a maximum supply current of 14 µA per channel, a propagation delay of 800 ns, and an input offset voltage of 4 mV. It supports an output sink current of 34 mA and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail input stage for full common-mode voltage range utilization
• Open-drain output configuration enabling wired-OR logic connections
• Ultra-low power consumption suitable for battery-operated systems
• Small SC-70 footprint designed for space-constrained PCB layouts

Applications

• Low-voltage portable electronic devices requiring minimal power draw
• Threshold detection circuits in battery-powered instrumentation
• Level-shifting applications utilizing the open-drain output flexibility
• Space-critical consumer electronics designs

Procurement Notes

Verify the specific suffix 'MF' against the manufacturer's official datasheet to confirm the exact tape-and-reel quantity and packaging variant. Ensure the ordering part number matches the required package style and environmental rating. Cross-reference with the LMV7275MG/NOPB designation if alternative packaging options are acceptable for the design.

Selection Notes

Select this component when a single comparator with rail-to-rail inputs and low quiescent current is required. The open-drain output necessitates an external pull-up resistor, which allows the output voltage to exceed the supply rail for level shifting. Consider the 800 ns propagation delay as the limiting factor for high-speed signal processing applications.

Part Context

This device belongs to the LMV727x family of low-power comparators manufactured by Texas Instruments. The family includes variants with push-pull outputs (LMV7271/2) and open-drain outputs (LMV7275). These components utilize a submicron silicon-gate BiCMOS process to balance low power consumption with improved noise performance compared to standard CMOS comparators.

FAQ

Can the LMV7275MF output voltage exceed the positive supply rail?

Yes, the open-drain output allows the device to be pulled up to any voltage up to 5.5 V, independent of the supply voltage powering the comparator.

What is the typical supply current for this device?

The device consumes as little as 9 µA per channel, with a maximum specified operating supply current of 14 µA.
