Overview
The LMV7271MG/NOPB is a single-channel analog comparator manufactured by Texas Instruments. It features rail-to-rail input capability and a push-pull output stage. The device operates within a supply voltage range of 1.8 V to 5.5 V, consuming a typical supply current of 9 µA per channel. Key electrical specifications include a propagation delay of 1.8 µs, an input offset voltage of 4 mV, and an input bias current of 10 nA. The common-mode rejection ratio is 46 dB, while the power supply rejection ratio is 55 dB. The maximum output current per channel is 34 mA. It functions reliably across an operating temperature range from -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.
- Ultra-low supply current consumption supports battery-powered and energy-efficient designs.
Applications
- Low voltage signal processing circuits
- Space-critical PCB designs requiring minimal footprint
- General purpose comparison tasks in portable electronics
Procurement Notes
Verify the specific suffix MG/NOPB against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required SC-70-5 package configuration. Cross-reference the manufacturer's official documentation for any recent design changes or lifecycle notices before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring rail-to-rail inputs combined with a push-pull output structure. It is suitable for designs needing low quiescent current and moderate speed performance. Consider alternative packages if larger footprints are acceptable, or different output types if wired-OR logic is required instead of active drive.
Part Context
This device belongs to the LMV727x family of low-power comparators built on submicron silicon-gate BiCMOS process technology. The family includes dual-channel variants like the LMV7272 and open-drain output versions such as the LMV7275. These components are designed to reduce PCB area through compact packaging options while maintaining bipolar input noise performance.
Replacement Considerations
LMV7271MFX/NOPB: Same functional device but in SOT-23-5 package instead of SC-70-5.
