Overview
The LM3302DRG4 is a quad differential analog comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a single supply voltage ranging from 2 V to 28 V with a typical quiescent current of 16 mA. The device features a response time of 300 ns and an input offset voltage of 20 mV. It supports CMOS and TTL output logic levels and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent differential comparators into a single compact package for space-constrained designs.
- Provides flexible digital interface compatibility through CMOS and TTL compatible output stages.
- Operates reliably across a wide industrial temperature range suitable for diverse environmental conditions.
Applications
- General-purpose signal processing circuits requiring multiple comparison functions
- Industrial control systems utilizing standard voltage thresholds
- Consumer electronics employing low-voltage power supplies
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and compliance status. Confirm that the component meets all required RoHS directives and material declarations for your target market. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications and pinout definitions before finalizing procurement orders.
Selection Notes
Select this component when a design requires four independent comparators within a limited board area. Consider its 2 V minimum operating voltage for battery-powered applications. Evaluate the 300 ns response time against signal frequency requirements. Ensure the system can accommodate the 16 mA quiescent current draw during active operation.
Part Context
This part belongs to the LM3302 series of quad differential comparators produced by Texas Instruments. It shares functional similarities with other members of the family while offering specific performance characteristics tailored for general-purpose analog comparison tasks. The DRG4 designation indicates a lead-free, halogen-free variant compliant with modern environmental standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official replacement guide or contact technical support directly for verified cross-reference information regarding equivalent components.
