Overview
The LM2903QM8-13 is a dual differential voltage comparator manufactured by Diodes Incorporated, housed in an MSOP-8 surface-mount package. 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 2mV and a maximum input bias current of 250nA at 5V. Supply current drain is 0.6mA at 5V. It supports an output sink current of 16mA and functions within an ambient temperature range of -40°C to +125°C.
Feature Summary
- Qualified to AEC-Q100 Grade 1 standards for automotive compliance
- Low power supply current independent of the magnitude of the power supply voltage
- Common-mode input voltage range includes ground potential
- Output voltage compatible with TTL, MOS, and CMOS logic families
Applications
- Motor control systems
- Instrumentation circuits
- Switch-mode power supplies
- Industrial process control
Procurement Notes
Verify that the component matches the specific Diodes Incorporated part number LM2903QM8-13. Confirm the MSOP-8 package code M8 and the -13 tape and reel suffix. Ensure the device meets AEC-Q100 Grade 1 requirements if used in automotive contexts. Check RoHS 3 and halogen-free status against project specifications.
Selection Notes
Select this component when a dual precision comparator with low offset voltage is required in a compact MSOP-8 footprint. It is suitable for designs needing direct interface with digital logic without additional level shifting. Consider the wide supply voltage range and low quiescent current for battery-powered or energy-efficient applications.
Part Context
This device belongs to the LM2903Q series of automotive-compliant dual differential comparators. It shares functional similarities with the LM2901Q quad version but provides two independent channels. The Q suffix indicates automotive qualification, while the M8 suffix specifies the MSOP-8 package type. It is designed for high-gain, wide-bandwidth performance in industrial and automotive environments.
