Overview
The LMV331SE-7 is a single-channel low-voltage analog comparator manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector output. The device consumes a typical supply current of 40 µA at 2.7 V and 60 µA at 5 V. Input offset voltage is guaranteed up to 7 mV, with input bias currents reaching 400 nA maximum across the full temperature range. Propagation delay varies between 200 ns and 1000 ns depending on overdrive conditions. It is housed in a 5-pin SOT-353 surface-mount package.
Feature Summary
- Low power consumption suitable for battery-operated applications
- Input common-mode voltage range includes ground potential
- Open collector output structure provides flexibility for various logic families
- Operates reliably across extended industrial temperature ranges
Applications
- Mobile communications equipment
- Battery powered devices
- Notebooks and PDAs
- General purpose portable devices
Procurement Notes
Verify that the component matches the specified SOT-353-5 package configuration. Confirm RoHS compliance and lead-free status as indicated in the manufacturer documentation. Ensure the ordering suffix corresponds to the tape and reel packaging format required for automated assembly processes.
Selection Notes
Select this comparator when space constraints require a compact SOT-353 footprint. It is appropriate for designs requiring low quiescent current and operation from a single 2.7 V to 5.5 V supply rail. Consider the open collector output requirement for external pull-up resistor selection based on the target load impedance.
Part Context
This component belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339 and LM393 comparators. While the LMV339 offers quad configurations and the LMV393 provides dual channels, the LMV331 specifically delivers a single comparator channel optimized for minimal board area usage in portable electronics.

FAQ
Does the input common-mode voltage range include ground?
Yes, the common-mode input voltage range extends from -0.1 V below the negative supply to within 0.8 V of the positive supply, allowing it to include ground.
What is the recommended value for the output pull-up resistor?
The datasheet recommends a pull-up resistor ranging between 1 kΩ and 10 kΩ to ensure proper switching while avoiding excessive power dissipation.
