LMV7275MGX

Overview

The LMV7275MGX is a single-channel, low-power analog comparator manufactured by Texas Instruments. It features rail-to-rail input capability and an open-drain output stage. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V. Key electrical specifications include a maximum quiescent current of 14 µA, a maximum propagation delay of 2.1 µs, and a maximum input offset voltage of 4 mV at 5 V. The input bias current is typically 0.01 µA at 5 V. It supports surface mount mounting in a SC-70-5 package and functions within an operating 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
• Low power consumption with minimal quiescent current draw
• CMOS-compatible output swing for direct interface with digital logic

Applications

• Level-shifting applications requiring output pull-up to voltages independent of the supply
• Space-critical designs utilizing compact SC-70-5 packaging
• Low voltage battery-powered systems requiring minimal standby current
• General-purpose threshold detection circuits

Procurement Notes

Verify the specific suffix 'G' and 'X' against the manufacturer's official datasheet to confirm package type and reel specifications. Ensure the NOPB designation aligns with lead-free requirements if applicable. Cross-reference the ordering part number with the latest Texas Instruments documentation to confirm active status and pinout compatibility before integration into production designs.

Selection Notes

Select this component when an open-drain output is required for wired-OR configurations or level shifting. It is suitable for designs needing rail-to-rail inputs but does not support push-pull outputs found in the LMV7271 variant. Consider the 2.1 µs propagation delay limit for timing-sensitive applications. Verify that the SC-70-5 package dimensions fit the available PCB real estate constraints.

Part Context

This device belongs to the LMV727x family of rail-to-rail input comparators. Unlike the LMV7271 which features a push-pull output, the LMV7275 specifically provides an open-drain output. The family utilizes a submicron silicon-gate BiCMOS process to achieve low power consumption while maintaining bipolar input noise performance characteristics.

FAQ

Can the LMV7275 output be pulled up to a voltage higher than its supply voltage?

Yes, the open-drain output allows the device to be pulled up to any voltage up to 5.5 V, regardless of the LMV7275's supply voltage.

What is the difference between LMV7275 and LMV7271 outputs?

The LMV7275 features an open-drain output suitable for wired-OR configurations, whereas the LMV7271 has a push-pull output stage.
