Overview
The LMV331M7X/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 operating supply current of 120 µA. The device features an open collector/open drain output type compatible with CMOS, TTL, and other logic families. Key electrical specifications include a maximum input offset voltage of 7 mV at 5 V and a maximum propagation delay of 600 ns. 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
- Low power consumption with 120 µA maximum supply current
- Open collector/open drain output for flexible logic interfacing
- Compact SC-70-5 surface-mount packaging
Applications
- General purpose signal comparison circuits
- Voltage monitoring applications
- Threshold detection systems
Procurement Notes
Verify the specific suffix configuration when ordering, as the LMV331M7X variant may have different environmental compliance status compared to the NOPB version. Confirm RoHS compliance requirements against the final part number designation before procurement. Ensure the SC-70-5 package footprint matches the target PCB layout. Check for any recent product change notices regarding manufacturing updates or material composition changes.
Selection Notes
Select this component for designs requiring low power operation and small form factor integration. The open collector output allows for easy level shifting to various logic voltages. Consider the 7 mV input offset voltage specification for precision requirements. Verify that the 600 ns propagation delay meets the timing constraints of the application. Ensure the operating temperature range aligns with the environmental conditions of the end-use system.
Part Context
The LMV331M7X/NOPB belongs to the LMV331 series of single comparators from Texas Instruments. This series is designed for low-voltage, low-power applications where space is limited. The device serves as a cost-effective solution for basic threshold detection tasks in consumer electronics and industrial control systems. It shares functional similarities with other members of the LMV family but offers specific performance characteristics tailored for general-purpose use.
Replacement Considerations
The LMV331M7X is listed as NRND (Not Recommended for New Designs) with the LMV331M7X/NOPB identified as the alternate. Verify pin compatibility and electrical specifications when substituting between these variants. Ensure that any replacement part maintains the same SC-70-5 package and output configuration.
