LMV331IDBVRE4

Overview

The LMV331IDBVRE4 is a single low-voltage 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 or open drain output capable of sourcing up to 10 mA per channel. Key electrical specifications include a maximum response time of 200 ns, an input offset voltage (Vos) of 7 mV, and an input bias current (Ib) of 250 nA. It is housed in a SOT-23-5 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Single-channel general-purpose analog comparator design optimized for low-voltage operation
• Open collector/open drain output configuration allowing flexible interfacing with various logic families
• Low power consumption profile suitable for battery-powered applications
• Extended industrial temperature rating ensuring reliable performance in harsh environments

Applications

• Threshold detection circuits
• Voltage monitoring systems
• Over/under voltage protection
• Window comparators

Procurement Notes

Verify the specific suffix RE4 indicates tape and reel packaging when ordering. Confirm RoHS compliance status as detailed in official documentation. Ensure the SOT-23-5 footprint matches the target PCB layout. Check for any recent Product Change Notifications regarding assembly sites or marking changes that may affect integration.

Selection Notes

Select this component when a single comparator with low quiescent current is required. The open-drain output necessitates an external pull-up resistor; ensure the chosen resistor value aligns with the desired switching speed and load requirements. Verify that the 7 mV input offset voltage meets the precision needs of the application.

Part Context

This part belongs to the LMV331 series of low-voltage comparators. It is designed to replace older bipolar comparators in modern low-power designs. The IDBVR package variant specifically denotes the SOT-23-5 form factor with specific thermal and mechanical characteristics defined by the manufacturer.

Replacement Considerations

Consult official cross-reference lists for direct pin-compatible alternatives. Verify that substitute parts maintain the same 2.7V to 5.5V supply range and SOT-23-5 package dimensions to ensure board compatibility without redesign.
