Overview
The LM2903S-13 is a dual differential voltage comparator manufactured by Diodes Incorporated, housed in an SO-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 of 7mV at 5V. Supply current is typically 0.6mA at 5V. Input bias current is 25nA typical, with an output sink current capability of 16mA. The operating temperature range extends from -40°C to +125°C.
Feature Summary
- Low power supply current independent of supply voltage magnitude
- Input common-mode voltage range includes ground potential
- Differential input voltage range equals the power supply voltage
- Output voltage compatible with TTL, MOS, and CMOS logic families
Applications
- Direct interface with TTL and CMOS logic circuits
- MOS logic interfacing where low power drain is advantageous
- Precision voltage comparison applications requiring wide supply range
Procurement Notes
Verify that the component matches the specific Diodes Incorporated datasheet DS36779 Rev 4. Confirm the SO-8 package type and tape & reel packaging suffix '-13'. Ensure the part number corresponds to the standard LM2903 grade rather than the A-grade variant for specified offset voltage parameters.
Selection Notes
Select this component when a dual comparator with wide single-supply operation is required. It is suitable for designs needing direct logic interfacing without additional level shifting. Consider the A-suffix version if lower input offset voltage specifications are critical for the application accuracy.
Part Context
This device belongs to the LM2901/2903 series of dual and quad differential comparators. The series is designed for high-gain, wide bandwidth performance. While similar to operational amplifiers, these devices are optimized for fast switching and open-collector output configurations rather than linear feedback operations.
Replacement Considerations

FAQ
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.
Is the output capable of driving multiple loads?
Yes, the open collector output allows multiple collectors to be tied together for ORing functions or driving various logic families.
