Overview
The LMV331IDBVT 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 quiescent 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 propagation delay of 200 ns, an input offset voltage of 7 mV, and an input bias current of 250 nA. It functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Single low-voltage comparator design optimized for battery-powered applications
- Open collector or open drain output configuration for flexible interfacing
- Extended industrial operating temperature range ensuring reliability in harsh environments
Applications
- Battery-operated consumer electronics
- Threshold detection circuits
- Simple on/off control systems
Procurement Notes
Verify the specific suffix 'G4' or 'E4' against the datasheet to confirm RoHS compliance status and manufacturing origin. Confirm that the SOT-23-5 package matches the PCB footprint requirements. Ensure the open-drain output logic levels are compatible with the downstream circuitry voltage domains before finalizing procurement.
Selection Notes
Select this component when a single comparator with low power consumption and wide temperature tolerance is required. The open-drain output allows for wired-OR configurations and level shifting. Compare against the LMV331IDBVR variant if reel packaging is preferred over cut tape. Consider the LMV339 series if multiple channels are needed.
Part Context
This part belongs to the LMV331 family of general-purpose low-voltage comparators from Texas Instruments. It is designed as a drop-in replacement for older bipolar comparators while offering significantly lower power consumption. The device is commonly used in portable devices where minimizing standby current is critical.
Replacement Considerations
Publicly confirmed substitute part numbers include LMV331IDBVR and LMV331IDBVTE4.
