Overview
The LP339D is a low-power quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 5 V to 30 V and features rail-to-rail output capability. The device includes four independent channels with a typical response time of 1.3 µs and an input offset voltage of 5 mV. Each channel supports an output current of 20 mA, while the total operating supply current is 25 µA. It functions reliably across a temperature range of 0°C to +70°C.
Feature Summary
- Quad differential architecture providing four independent comparison channels
- Low-power operation suitable for energy-efficient designs
- Rail-to-rail output interface compatible with various logic families
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring systems requiring low power consumption
- Threshold detection applications in industrial control
Procurement Notes
Verify the specific suffix 'DR' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements as indicated in manufacturer datasheets. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a quad comparator with low quiescent current is required. The SOIC-14 package suits surface-mount assembly processes. Compare performance metrics such as response time and input offset voltage against alternative parts if higher speed or precision is needed. Confirm thermal management capabilities for the intended operating environment.
Part Context
The LP339D belongs to the LP339 family of low-power quad comparators from Texas Instruments. It serves as a surface-mount variant of through-hole options like the LP339N. This series is designed for general-purpose applications where power efficiency and multiple comparison channels are prioritized over high-speed switching.
Replacement Considerations
Public confirmed substitute part numbers: None identified.
