Overview
The LM293DGKRG4 is a dual differential voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 36 V on a single supply or ±1 V to ±18 V on dual supplies. The device features an open-collector output capable of sinking up to 6 mA per channel. Key electrical specifications include a typical response time of 300 ns, a maximum input offset voltage of 5 mV at 30 V, and a maximum input bias current of 250 nA. It functions reliably across an operating temperature range of -40 °C to +125 °C.
Feature Summary
- Dual differential input configuration for precise signal comparison
- Open-collector outputs compatible with CMOS and TTL logic families
- Wide single-supply voltage operation from 2 V to 36 V
- Extended industrial temperature range capability
Applications
- Overvoltage and undervoltage detection circuits
- Window comparator designs
- Threshold detection systems
- Level shifting applications
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance details. Confirm the package designation matches the required SOIC-8 footprint. Ensure the order quantity aligns with the standard reel packaging specifications provided in the official datasheet.
Selection Notes
Select this component when a dual-channel comparator with wide supply voltage tolerance is required. The open-collector output allows for flexible interfacing with various logic levels. Consider the 300 ns propagation delay for timing-sensitive applications. Verify that the 6 mA output current meets the load requirements of the target circuit design.
Part Context
This part belongs to the LMx93 family of dual differential comparators from Texas Instruments. These devices are designed for general-purpose voltage comparison tasks using single or dual power supplies. The family includes variants such as the LM193, LM293, LM393, and LM2903, offering similar functional characteristics with variations in temperature ranges and automotive qualification.
Replacement Considerations
Publicly confirmed substitute part numbers for the LM293DGKRG4 were not identified in the available source material.
