Overview
The LM339DR2GH is a quad differential analog comparator manufactured by onsemi, housed in a 14-pin SOP package. It operates within a supply voltage range of 18 V to 36 V and features rail-to-rail output capability. Key electrical specifications include a typical response time of 1.3 µs, an input offset voltage of 5 mV, and an input bias current of 250 nA. The device supports a maximum power dissipation of 570 mW and functions reliably across a temperature range of -25°C to +85°C.
Feature Summary
- Integrates four independent differential comparators into a single compact package for space-efficient circuit designs.
- Provides rail-to-rail output swing capabilities to maximize signal utilization across the supply voltage range.
- Features low input bias current characteristics suitable for high-impedance sensor interfaces.
Applications
- Over-voltage and under-voltage protection circuits
- Threshold detection systems
- Analog-to-digital converter front-ends
Procurement Notes
Verify the specific suffix DR2GH against the required datasheet revision to ensure compatibility with existing design parameters. Confirm that the SOP-14 package dimensions match the target PCB footprint. Check RoHS compliance documentation for regulatory adherence. Validate the operating temperature range requirements against the specified -25°C to +85°C limit before finalizing procurement decisions.
Selection Notes
Select this component when a quad comparator configuration is required within a limited board area. Ensure the application voltage does not exceed the 36 V maximum rating. Consider the 1.3 µs response time for speed-sensitive applications. Verify that the 18 mA output current capability meets the load requirements of the downstream circuitry without external buffering.
Part Context
This part belongs to the LM339 series of analog comparators from onsemi. It serves as a commercial-grade alternative to industrial variants, offering similar functional performance within a restricted temperature window. The device is designed for general-purpose comparison tasks where cost-effectiveness and standard packaging are prioritized over extreme environmental resilience.
Replacement Considerations
The LM339DR2G is a related variant within the same product family. Verify pinout and electrical specifications before substitution. No other direct public substitutes are confirmed in the provided data.
