LMV7275MFX/NOPB

Overview

The LMV7275MFX/NOPB is a single-channel analog comparator from Texas Instruments, characterized by rail-to-rail input capability and low power consumption. It operates within a supply voltage range of 1.8 V to 5.5 V, drawing a typical quiescent current of 14 µA per channel. The device features an open-drain output stage capable of sourcing up to 34 mA. Key electrical parameters include a maximum input offset voltage of 4 mV, an input bias current of 10 nA, and a propagation delay of approximately 800 ns. It supports a common-mode rejection ratio (CMRR) of 46 dB and a power supply rejection ratio (PSRR) of 55 dB. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Rail-to-rail input stage enables accurate signal comparison near supply rails
• Open-drain output allows flexible level-shifting and wired-OR configurations
• Ultra-low power consumption suitable for battery-operated applications

Applications

• Low voltage portable electronics
• Level shifting circuits
• Battery-powered monitoring systems

Procurement Notes

Verify the specific suffix 'MFX' corresponds to the SOT-23-5 package variant when ordering. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance as per manufacturer specifications. Ensure the selected distributor provides genuine Texas Instruments components with traceable documentation to guarantee authenticity and performance reliability in final assembly.

Selection Notes

Select this component when space-constrained designs require a single comparator with rail-to-rail inputs. The open-drain output is advantageous for interfacing with different logic voltage levels without additional components. Consider the 14 µA supply current for strict power budgeting. Verify that the 4 mV offset voltage meets the precision requirements of the specific application circuit.

Part Context

This part belongs to the LMV727x family of low-power comparators manufactured using submicron silicon-gate BiCMOS process. The family includes variants with push-pull outputs, such as the LMV7271, while the LMV7275 specifically offers an open-drain configuration. These devices are designed to minimize PCB area through compact SC-70 and SOT-23 packaging options.

Replacement Considerations

LMV7275MGX/NOPB is a verified equivalent offering identical functionality in the SC-70-5 package.
