LMV339MTX

Overview

The LMV339MTX is a quad general-purpose low-voltage analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V, offering lower current consumption compared to standard LM339 devices. The component features an open-drain output structure and rail-to-rail input common-mode capability that includes ground potential. Designed for space-constrained applications, it utilizes a compact surface-mount package suitable for automated assembly processes.

Feature Summary

• Low voltage operation optimized for single-supply systems
• Quad channel configuration in a tiny surface-mount package
• Rail-to-rail input common-mode range including ground

Applications

• Battery-powered portable electronics
• Signal conditioning circuits
• Space-constrained embedded systems

Procurement Notes

Verify the specific suffix 'MTX' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications and exact temperature grade. Ensure compatibility with existing PCB footprints and reflow soldering profiles defined in the manufacturer's datasheet before finalizing procurement orders.

Selection Notes

Select this component when system power budgets require operation below 3.3 V or 5 V rails. The open-drain output necessitates external pull-up resistors; verify logic level requirements of downstream digital interfaces. Consider thermal dissipation limits if multiple channels operate simultaneously under heavy load conditions.

Part Context

This device belongs to the LMV3xx family, which serves as the low-voltage counterpart to the industry-standard LM339/LM393 comparators. While maintaining functional compatibility, the LMV series provides reduced quiescent current and extended input common-mode range down to ground, facilitating direct interfacing with microcontrollers and sensors in modern low-power designs.
