Overview
The LP339N/PB is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin PDIP package. It operates within a supply voltage range of 2V to 36V and features an ultra-low power consumption profile with a typical operating current of 25µA. The device provides rail-to-rail output capability and supports a maximum output current of 20mA per channel. Key electrical specifications include a response time of 8µs, an input offset voltage of 5mV, and an input bias current of 25nA. It functions reliably across a temperature range of 0°C to +70°C.
Feature Summary
- Ultra-low power consumption suitable for battery-operated applications
- Quad differential configuration for multi-channel signal processing
- Rail-to-rail output capability for flexible interfacing
Applications
- Battery-powered monitoring systems
- General-purpose voltage threshold detection
- Low-power analog signal conditioning
Procurement Notes
Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets RoHS requirements if applicable to the target assembly. Cross-reference the part number with the latest datasheet to validate performance parameters before integration into the design.
Selection Notes
Select this component when low quiescent current is critical compared to standard comparators like the LM339. Verify that the 8µs response time meets the application's speed requirements. Confirm that the 14-PDIP package fits the available PCB footprint and that the 2V minimum supply voltage aligns with the system's power rails.
Part Context
This part belongs to the LP339 family of ultra-low power quad comparators from Texas Instruments. It serves as a low-power alternative to the LM339 series, offering reduced current consumption while maintaining similar functional capabilities. The device is designed for general-purpose applications where power efficiency is a primary constraint.
Replacement Considerations
LP339N/NOPB is a direct replacement variant.
