LM2903BIDSGR

Overview

The LM2903BIDSGR is a dual voltage comparator from Texas Instruments, part of the B-version family. It operates on a single supply voltage ranging from 2V to 36V. The device features an input offset voltage of ±4mV over temperature and a typical response time of 1µsec. It includes dedicated ESD clamps providing 2kV HBM protection. The component utilizes a VSSOP-8 package with dimensions of 3.00mm x 3.00mm.

Feature Summary

• Improved specifications including lower offset voltage and faster response time compared to previous versions
• Enhanced ruggedness through dedicated ESD clamps for improved input protection
• Low quiescent current consumption that remains independent of the supply voltage
• Common-mode input voltage range extends to include the negative rail

Applications

• Vacuum robot systems
• Single phase UPS units
• Server power supply designs
• Cordless power tools
• Wireless infrastructure equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official orderable addendum to confirm the exact package type and tape/reel specifications. Ensure the procurement documentation matches the required industrial temperature range and electrical characteristics defined in the datasheet.

Selection Notes

Select this component when drop-in replacement for legacy LM2903 or LM393 devices is required with enhanced performance. Consider the B-version benefits such as higher maximum supply voltage capability and reduced input bias current for precision applications requiring low power consumption.

Part Context

This device belongs to the LMx93B and LM2903B next-generation comparator family. These parts are designed to replace industry-standard A and V grades while offering superior electrical parameters. The family supports various packages including SOIC, VSSOP, TSSOP, SOT-23, and WSON configurations.

Replacement Considerations

The LM2903B serves as a direct drop-in replacement for the LM293, LM393, and LM2903 in both A and V grades.
