Overview
The LP339N/NOPB is an ultra-low power quad comparator manufactured by Texas Instruments. It features four independent differential comparators in a single 14-PDIP package. The device operates with a supply voltage range of 2 V to 36 V and draws only 25 uA of operating current. Key electrical parameters include an 8 us response time, 20 mA output current capability per channel, 5 mV input offset voltage, and 25 nA input bias current. It supports rail-to-rail outputs and functions within a commercial temperature range of 0 C to +70 C.
Feature Summary
- Ultra-low power consumption for battery-operated applications
- Quad differential comparator configuration
- Wide single-supply voltage operation
- Rail-to-rail output capability
Applications
- Battery-powered monitoring systems
- General-purpose signal comparison
- Threshold detection circuits
- Low-power analog signal processing
Procurement Notes
Verify the specific suffix NOPB indicates lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the PDIP-14 through-hole package matches your PCB footprint requirements. Ensure the 2 V to 36 V supply range aligns with your system design constraints. Check the commercial temperature grade (0 C to +70 C) against environmental specifications.
Selection Notes
Select this component when low quiescent current is critical compared to standard LM339 variants. The LP339N/NOPB offers significantly reduced power draw while maintaining comparable speed and output drive capabilities. Consider the rail-to-rail output feature if interfacing with CMOS logic levels directly without additional pull-up resistors. Verify that the 14-PDIP package is suitable for your assembly process.
Part Context
The LP339 series represents Texas Instruments' low-power evolution of the industry-standard LM339 quad comparator. The NOPB suffix denotes a lead-free and RoHS-compliant version of the standard LP339N. This part maintains functional compatibility with legacy designs while offering improved power efficiency for modern energy-conscious applications.
