Overview
The LP339DG4 is a quad general-purpose analog comparator manufactured by Texas Instruments in a 14-SOIC surface-mount package. It operates on a single supply voltage ranging from 5 V to 30 V, with a typical quiescent current of 25 µA per channel. The device features rail-to-rail outputs capable of sourcing 20 mA and offers a response time of 1.3 µs. Input specifications include a maximum input offset voltage of 5 mV and an input bias current of 25 nA. It functions within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Integrates four independent differential comparators in a compact surface-mount package for space-constrained designs.
- Provides rail-to-rail output capability to maximize signal swing across the full supply voltage range.
- Features low power consumption suitable for battery-operated or energy-efficient applications.
Applications
- General-purpose voltage monitoring circuits
- Threshold detection systems
- Simple logic interface adapters
Procurement Notes
Verify the specific suffix 'DG4' confirms the 14-SOIC package and lead-free composition as documented by Texas Instruments. Confirm RoHS compliance status through official manufacturer datasheets or authorized distributor certificates prior to procurement. Ensure the component source is traceable to avoid counterfeit risks associated with obsolete or legacy part numbers.
Selection Notes
Select this component when a quad comparator configuration is required in a surface-mount form factor. It is appropriate for designs needing rail-to-rail output swings and low static current draw. Verify that the 1.3 µs response time meets the speed requirements of the target application compared to faster alternatives if necessary.
Part Context
The LP339DG4 belongs to the LP339 family of linear comparators from Texas Instruments. It serves as the surface-mount SOIC variant of the through-hole LP339N. This series provides a cost-effective solution for basic comparison tasks where high-speed performance is not the primary constraint.
Replacement Considerations
The LP339DR is the tape-and-reel version of the same die and package. Cross-reference with other quad comparators only if pin compatibility and electrical parameters match exactly.
