LM2903BIDGKR

Overview

The LM2903BIDGKR is a dual differential voltage comparator from the LMx93/LM2903 family, manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2V to 36V. The device features an input common-mode voltage range that includes ground and a differential input voltage range equal to the maximum-rated supply voltage of ±38V. It provides open-collector outputs compatible with TTL, MOS, and CMOS logic families. The component supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Next-generation B-version design offering improved electrical specifications over standard versions
• Enhanced input ruggedness with dedicated ESD clamps providing 2kV HBM protection
• Low quiescent current consumption independent of supply voltage
• Open-collector output structure allowing direct interface with various logic families

Applications

• Vacuum robot systems
• Single phase UPS units
• Server power supply circuits
• Cordless power tools
• Motor drives

Procurement Notes

Verify the specific package type and suffix against the manufacturer's latest orderable addendum to ensure compatibility with your PCB footprint. Confirm that the B-version characteristics align with your system requirements for offset voltage and propagation delay. Check for any regional compliance certifications required for your target market before finalizing procurement.

Selection Notes

Select this component when higher precision and faster response times are needed compared to standard LM2903 devices. The B-version offers lower input offset voltage and bias current, making it suitable for sensitive signal comparison tasks. Ensure the application benefits from the extended temperature range and improved ESD robustness provided by this generation.

Part Context

This part belongs to the LMx93/LM2903 series of dual comparators designed for wide voltage range single-supply operation. The LM2903B represents the next generation of this industry-standard family, featuring enhanced performance metrics while maintaining pin compatibility with previous A and V grades for drop-in replacement scenarios in existing designs.

Replacement Considerations

LM2903B can serve as a drop-in replacement for LM293, LM393, and LM2903 variants including A and V grades.
