LMV331IDBVRG4

Overview

The LMV331IDBVRG4 is a single-channel general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes a typical operating current of 100 µA. The device features an open collector/open drain output capable of sourcing up to 10 mA. Key electrical specifications include a maximum response time of 200 ns, an input offset voltage of 7 mV, and an input bias current of 250 nA. It supports differential input types and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Low-voltage operation optimized for battery-powered applications
• High-speed response with 200 ns propagation delay
• Open collector/drain output interface for flexible logic compatibility

Applications

• Threshold detection circuits
• Voltage monitoring systems
• General-purpose signal comparison tasks

Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the SOT-23-5 package variant matches the required PCB footprint and thermal management constraints for the specific design implementation.

Selection Notes

Select this component when low power consumption and wide temperature stability are critical requirements. The open-drain output allows for easy interfacing with various logic families without level shifting issues. Ensure the application does not require rail-to-rail output swing, as this model utilizes an open collector configuration.

Part Context

This device belongs to the LMV331 family of general-purpose low-voltage comparators. It shares functional similarities with other members like the LMV331IDBVRE4 but may differ in specific packaging or environmental certifications. The IDBVR designation indicates the industrial temperature grade and surface-mount SOT-23-5 package type.

Replacement Considerations

LMV331IDBVRE4 serves as a verified alternative within the same product family.
