LM393DGKRG4

Overview

The LM393DGKRG4 is a dual differential analog comparator manufactured by Texas Instruments, belonging to the LM393A series. It features an open-collector output compatible with CMOS and TTL logic families. The device operates within a supply voltage range of 2 V to 36 V (single) or ±1 V to ±18 V (dual). Key electrical specifications include a maximum input offset voltage of 5 mV at 30 V, a typical quiescent current of 2.5 mA, and a response time of 1.3 µs. It supports rail-to-rail output swing and functions across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel differential comparison architecture
• Open-collector output compatible with standard logic families
• Wide single or dual power supply operation capability

Applications

• Over/under voltage detection circuits
• Temperature sensing threshold monitoring
• Window comparator configurations

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to project requirements. Review the latest datasheet for any recent package or electrical specification updates before finalizing procurement plans.

Selection Notes

Select this component when dual independent comparators are required in a compact surface-mount package. Ensure the application does not demand push-pull outputs, as this device utilizes open-collector topology. Verify that the system load can accommodate the specified sink current capabilities under all operating conditions.

Part Context

This part is a variant of the industry-standard LM393 family, specifically packaged in an 8-VSSOP housing. It serves as a cost-effective solution for general-purpose signal conditioning and threshold detection tasks where high precision is not the primary design constraint.

Replacement Considerations

LM393DGKR is a verified substitute offering identical functionality and pinout compatibility within the same package type.
