Overview
The LP339DE4 is a quad differential analog comparator manufactured by Texas Instruments, belonging to the LP339 series. It features four independent channels housed in a 14-pin SOIC surface-mount package. The device operates with a supply voltage range of 2 V to 36 V and draws an operating supply current of 25 uA. Key electrical specifications include a response time of 8 us, an input offset voltage of 5 mV, and an input bias current of 25 nA. Each channel provides a rail-to-rail output capable of sourcing up to 20 mA. The component supports through-hole or surface-mount installation depending on the specific variant configuration and functions within a temperature range of 0 C to +70 C.
Feature Summary
- Quad differential architecture providing four independent comparison channels
- Ultra-low power consumption suitable for battery-operated applications
- Rail-to-rail output capability for maximum dynamic range
- General-purpose design compatible with standard logic families
Applications
- Battery-powered monitoring systems
- Over-voltage and under-voltage protection circuits

Procurement Notes
Verify the exact suffix designation against the manufacturer's official documentation to confirm pinout compatibility and environmental compliance status. Ensure the selected package variant matches the intended PCB layout requirements. Cross-reference the specific ordering code with the latest datasheet revision to validate performance parameters and RoHS status before finalizing procurement decisions.
Selection Notes
Select this component when low quiescent current is critical alongside quad-channel functionality. Compare input offset voltage and response time requirements against application needs. Consider the SOIC package dimensions for space-constrained designs. Evaluate thermal dissipation capabilities relative to the expected load conditions and ambient operating temperatures.
Part Context
The LP339DE4 is part of the broader LP339 family of ultra-low power quad comparators. This series is designed to offer high performance while minimizing power consumption. The DE4 suffix typically indicates a specific lead-free and environmental compliance variant within the Texas Instruments portfolio, distinguishing it from older non-compliant versions.
