Overview
The LM2903AM8-13 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 very low supply current drain independent of voltage magnitude and includes an input common-mode range that extends to ground. It provides open-collector outputs compatible with TTL, MOS, and CMOS logic families.
Feature Summary
- Features extremely low typical offset voltage for precision applications
- Offers wide power supply range supporting both single and split configurations
- Provides direct interface capability with standard digital logic families
Applications
- Motor control systems
- Instrumentation circuits
- Switch-mode power supplies
- Industrial process control
Procurement Notes
Verify the specific ordering suffix matches the required package type and tape-and-reel quantity. Confirm compliance with RoHS directives and halogen-free requirements as specified in the manufacturer's documentation. Ensure the component grade aligns with the intended operational temperature range and performance specifications.
Selection Notes
Select this variant when a compact MSOP-8 footprint is required alongside high-precision comparison capabilities. The A-suffix indicates a tighter offset voltage specification compared to standard versions. Consider the open-collector output structure for flexible pull-up voltage selection across different logic levels.
Part Context
This component belongs to the LM2901/2903 series of dual and quad differential comparators. The series is designed for low-power operation with minimal supply current draw regardless of the applied voltage level. It utilizes industry-standard pinouts across various package options including SO-8, TSSOP-8, and MSOP-8.

FAQ
What is the typical input offset voltage for the LM2903A?
The typical input offset voltage for the A-device is 1mV at +25°C.
Can the differential input voltage exceed the supply voltage?
Yes, the differential input voltage range equals the power supply voltage, allowing inputs to exceed VCC without damage provided other voltages remain within limits.
