LMV7271MG

Overview

The LMV7271MG/NOPB is a single-channel analog comparator from Texas Instruments, housed in an SC-70-5 surface-mount package. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical quiescent current of 9 µA per channel. The device features rail-to-rail input capability with a maximum input offset voltage of 4 mV and an input bias current of 10 nA. It provides a push-pull output stage capable of sourcing or sinking up to 34 mA. Key performance metrics include a propagation delay of 1.8 µs, 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 operating temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail input stage enables full signal swing utilization across the entire supply voltage range.
• Push-pull output architecture supports direct driving of loads without requiring external pull-up resistors.
• Ultra-low power consumption design allows operation with minimal supply current for battery-sensitive applications.

Applications

• Level-shifting circuits requiring interface between different voltage domains
• Space-constrained portable electronic designs
• Low-voltage threshold detection systems

Procurement Notes

Verify that the ordering suffix matches /NOPB to ensure compliance with RoHS standards and lead-free manufacturing processes. Confirm the package designation corresponds to SC-70-5 for physical compatibility. Ensure the manufacturer identification aligns with Texas Instruments specifications. Cross-reference the Mouser part number 926-LMV7271MG/NOPB for accurate procurement tracking. Validate that the component meets the required industrial temperature ratings for your specific deployment environment.

Selection Notes

Select this component when designing low-power systems requiring rail-to-rail input sensitivity. The push-pull output is suitable for applications needing active drive capabilities without external components. Consider the 1.8 µs response time for general-purpose timing requirements. Evaluate the 34 mA output current capacity against load demands. Verify that the SC-70-5 footprint fits within the available PCB area constraints.

Part Context

This device belongs to the LMV727x family of rail-to-rail input low-power comparators. The family includes single-channel variants like the LMV7271 and dual-channel versions such as the LMV7272. These devices utilize a submicron silicon-gate BiCMOS process to balance noise performance with power efficiency. The LMV7271 specifically offers a push-pull output, distinguishing it from open-drain variants in the same series.

Replacement Considerations

Publicly confirmed substitute part numbers are not identified in the provided documentation. Designers should consult official Texas Instruments resources for qualified alternatives.
