Overview
The LM2903AQM8-13 is an automotive-compliant dual differential voltage comparator manufactured by Diodes Incorporated. It operates from a single supply of 2V to 36V or split supplies of ±1V to ±18V. The device features a typical input offset voltage of 1mV, low input bias current of 25nA, and very low supply current drain independent of voltage. Qualified to AEC-Q100 Grade 1, it supports temperatures from -40°C to +125°C and utilizes an MSOP-8 package.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- Ultra-low input offset voltage specification for precision applications
- Supply current remains stable regardless of power supply magnitude
- Open-collector outputs compatible with TTL, MOS, and CMOS logic
Applications
- Automotive sensor signal conditioning
- Window comparator circuits
- Over-voltage and under-voltage detection systems
- Threshold detection in battery management units
Procurement Notes
Verify the specific ordering suffix matches the required package type and tape-and-reel quantity. Confirm that the component meets the necessary AEC-Q100 reliability standards for your target application. Ensure compatibility with RoHS and halogen-free requirements if mandated by your manufacturing process specifications.
Selection Notes
Select this part when high precision is required due to its low offset voltage characteristics. It is suitable for designs needing wide supply voltage flexibility without increased power consumption. Consider the MSOP-8 package constraints regarding thermal dissipation and board space availability during layout planning.
Part Context
This component belongs to the LM2903Q/AQ series of dual comparators designed specifically for automotive environments. It shares functional similarities with standard industrial comparators but includes enhanced testing and quality controls required for automotive grade reliability and long-term stability.
Replacement Considerations
Direct replacements include other LM2903 variants from different manufacturers that meet AEC-Q100 standards. Verify pinout compatibility and ensure equivalent electrical parameters such as offset voltage and supply current range are maintained.
FAQ
What is the maximum differential input voltage allowed?
The differential input voltage can equal the entire power supply voltage range without damaging the device.
Can the common-mode input voltage go negative?
No, the common-mode input voltage should not go negative by more than 0.3V at room temperature.
