Overview
The LMP7300MAX/NOPB is a micropower precision comparator manufactured by Texas Instruments. It integrates an adjustable hysteresis function and a precision reference within a single 8-SOIC package. The device operates across an extended temperature range of -40°C to +125°C. Key electrical characteristics include low supply current consumption, high input impedance, and precise threshold detection capabilities suitable for battery-powered applications.
Feature Summary
- Integrates adjustable hysteresis to prevent output oscillation during noisy signal transitions
- Includes an internal precision reference for stable threshold setting without external components
- Designed for micropower operation to extend battery life in portable systems
Applications
- Battery-operated monitoring circuits
- Threshold detection in sensor interfaces
- Over-voltage or under-voltage protection schemes
Procurement Notes
Verify the specific suffix 'MAX' against the manufacturer's official documentation to confirm package type and thermal rating. Ensure the 'NOPB' designation aligns with current RoHS compliance requirements. Cross-reference the full part number with the latest datasheet revision to confirm availability and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when design requirements demand low power consumption alongside precise voltage comparison. The integrated hysteresis reduces the need for external feedback resistors, simplifying the schematic. Consider the 8-SOIC package constraints regarding thermal dissipation and board space. Verify that the input common-mode range and output swing meet the specific interface requirements of the downstream circuitry.
Part Context
This part belongs to the LMP7300 series of micropower comparators from Texas Instruments. The series is characterized by its combination of precision performance and ultra-low power consumption. The MAX variant specifically denotes the SOIC-8 package option, distinguishing it from other package styles like MSOP or DSBGA available within the same functional family.
