LMV331IDBVR

Overview

The LMV331IDBVR is a single general-purpose low-voltage comparator from Texas Instruments, housed in a compact SOT-23-5 surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical quiescent current of 100 µA. The device features an open-collector output capable of sinking up to 10 mA, allowing flexible interfacing with various logic families. Key electrical specifications include a maximum input offset voltage of 7 mV and an input bias current of 250 nA. It provides a response time of 200 ns and functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Low-power operation with minimal quiescent current consumption suitable for battery-powered applications
• Open-collector output configuration providing flexibility for level shifting and driving external loads
• Wide single-supply voltage range enabling compatibility with standard 3 V and 5 V systems
• Extended industrial temperature rating ensuring stable performance in harsh environments

Applications

• Industrial control systems requiring precise signal monitoring
• Test and measurement equipment needing accurate threshold detection
• Consumer electronics utilizing low-voltage power supplies

Procurement Notes

Verify the specific suffix 'DBVR' confirms the SOT-23-5 package and tape-and-reel delivery format. Ensure the component meets RoHS compliance requirements if mandated by your assembly process. Cross-reference the manufacturer part number against official Texas Instruments documentation to confirm pinout alignment and electrical characteristics match your design specifications before finalizing procurement.

Selection Notes

Select this component when a single-channel comparator with low power consumption and wide supply voltage tolerance is required. The open-collector output is ideal for interfacing with different logic levels without additional level-shifting circuitry. Consider the SOT-23-5 package size constraints and the need for an external pull-up resistor for proper high-state output definition during circuit design.

Part Context

This device belongs to the LMV331 series of low-voltage comparators designed for space-constrained applications. It serves as a cost-effective solution for general-purpose switching tasks where power efficiency and small footprint are critical. The series is engineered to replace older bipolar comparators in modern portable and industrial designs.

Replacement Considerations

The LMV331IDBVRG4 is a verified lead-free variant of the same functional device. Verify that any alternative replacement maintains identical pinout, electrical parameters, and thermal characteristics to ensure direct interchangeability without redesigning the surrounding circuitry.
