Overview
The LM2903M8-13 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. Supply current drain is 0.6mA at 5V and 0.7mA at 30V. The output sink current reaches 16mA with a saturation voltage of 200mV at 4mA. It supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Low power supply current independent of the magnitude of the power supply voltage
- Input common-mode voltage range includes ground potential
- Differential input voltage range equal to the power supply voltage
- Output voltage compatible with TTL, MOS, and CMOS logic families
Applications
- Motor control systems
- Instrumentation systems
- Switch-mode power supplies
- Industrial process control
Procurement Notes
Verify that the component matches the specific Diodes Incorporated LM2903M8-13 designation. Confirm the MSOP-8 package type and tape-and-reel packaging suffix. Ensure compliance with RoHS and lead-free requirements as specified in the manufacturer documentation. Cross-reference datasheet DS36779 for accurate electrical limits.
Selection Notes
Select this component when a low-power, wide-voltage-range dual comparator is required. The MSOP-8 package suits space-constrained designs. Verify that the 200mV output saturation voltage meets load requirements. Consider the 250nA maximum input bias current for high-impedance signal sources. Ensure the application does not exceed the absolute maximum ratings.
Part Context
This part belongs to the LM2901/2903 series of precision voltage comparators. The series offers low input offset voltage and low supply current. Dual devices are available in SO-8, TSSOP-8, and MSOP-8 packages. Quad versions exist in SO-14 and TSSOP-14 formats. All variants share industry-standard pinouts and green mold compound construction.

FAQ
Can the differential input voltage exceed the supply voltage?
Yes, the differential input voltage can be larger than VCC without damaging the device.
Is hysteresis required for stable operation?
Hysteresis is recommended to prevent oscillation caused by stray capacitance coupling between the output and inputs during voltage transitions.
