Overview
The LMV331M7/NOPB 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 maximum static current of 120 µA. The device features an open collector output compatible with CMOS, TTL, and other logic families. Key electrical specifications include a maximum input offset voltage of 7 mV at 5 V, a maximum propagation delay of 600 ns, and a typical output current capability of 84 mA at 5 V. It is housed in a compact SC-70-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Single-channel general-purpose analog comparator design
- Open collector output interface supporting multiple logic families
- Low power consumption suitable for battery-operated applications
Applications
- Threshold detection circuits
- Voltage monitoring systems
- Simple on/off control loops
Procurement Notes
Verify the specific suffix 'M7' against the manufacturer's official documentation to confirm pinout compatibility and functional equivalence with the standard LMV331 series. Confirm RoHS compliance status directly with the supplier or datasheet, as packaging variations may affect regulatory markings. Ensure the component source is authorized to avoid counterfeit risks given the component's age.
Selection Notes
Select this component when a low-cost, single-channel comparator with open-drain output is required. It is appropriate for designs where propagation delay is not critical and low quiescent current is a priority. Verify that the load can be driven by an open-collector structure and that the supply voltage remains within the specified 2.7 V to 5.5 V range.
Part Context
This part belongs to the LMV331 family of comparators from Texas Instruments. The 'M7' suffix indicates a specific tape-and-reel packaging configuration using the SC-70-5 package. The '/NOPB' designation typically signifies a lead-free and halogen-free version compliant with environmental standards, distinguishing it from older non-compliant variants.
Replacement Considerations
Public sources indicate the LMV331M7X/NOPB as an alternate designation for this component. Verify cross-reference compatibility with other single-channel comparators from different manufacturers if sourcing is restricted.
