Overview
The LM339AN/NOPB is a low-power, low-offset voltage quad comparator manufactured by Texas Instruments. It features four independent differential comparators in a single 14-pin PDIP package. The device operates on a single or dual power supply ranging from 2 V to 36 V. Key electrical specifications include a maximum input offset voltage of 5 mV, an operating supply current of 500 uA, and a response time of 700 ns. Each channel provides an output current capability of 6 mA with rail-to-rail output functionality.
Feature Summary
- Integrates four independent differential comparators within a single integrated circuit package for space-efficient designs.
- Operates across a wide supply voltage range from 2 V to 36 V, supporting both single and dual power configurations.
- Features low power consumption characteristics with an operating supply current of 500 uA.
- Provides rail-to-rail output capability for flexible interfacing with various logic families.
Applications
- Temperature sensing circuits utilizing thermistor bridges
- Over-voltage and under-voltage protection systems
- Window comparator applications for voltage monitoring
Procurement Notes
Verify the specific suffix 'NOPB' to confirm lead-free compliance and RoHS status as indicated in official documentation. Ensure the ordering part number matches the exact package style required for the target PCB footprint. Confirm that the 14-pin DIP configuration aligns with the assembly process before finalizing procurement orders.
Selection Notes
Select this component when multiple independent comparison functions are required in a compact through-hole package. Consider the 5 mV maximum input offset voltage for applications requiring moderate precision. Evaluate the 700 ns response time against signal frequency requirements to ensure adequate speed for the intended application dynamics.
Part Context
This component belongs to the LM339 family of analog comparators produced by Texas Instruments. It serves as a direct replacement for older non-compliant versions while maintaining pin compatibility. The device is categorized under analog comparators and is designed for general-purpose comparison tasks in industrial and consumer electronics.
