Overview
The LM2903DR-NG is a dual voltage comparator from Texas Instruments, part of the automotive-grade LM2903-Q1 family. It operates on a single supply ranging from 2V to 30V or dual supplies within the same differential range. The device features an open-drain output compatible with TTL, MOS, and CMOS logic families. It supports a wide operating temperature range from -40°C to +125°C and includes AEC-Q100 qualification for Grade 1 applications.
Feature Summary
- AEC-Q100 qualified for automotive environments with extended temperature reliability
- Open-drain outputs allow flexible logic level shifting and wired-AND configurations
- Wide common-mode input voltage range includes ground potential
Applications
- Automotive body control modules
- Infotainment systems and instrument clusters
- Industrial general-purpose signal comparison
Procurement Notes
Verify the specific suffix 'NG' against the manufacturer's official orderable addendum to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required thermal performance and ESD protection levels for the target application environment.
Selection Notes
Select this component when an automotive-qualified, low-power dual comparator is required. It serves as a drop-in replacement for standard LM2903 devices in designs needing higher reliability and wider supply voltage tolerance. Consider the open-drain output requirement for pull-up resistor implementation.
Part Context
This device belongs to the LM2903-Q1 family, designed for cost-sensitive automotive applications. It offers improved robustness compared to non-automotive counterparts while maintaining compatibility with industry-standard pinouts and electrical characteristics for easy integration into existing schematics.
