Procurement Notes

Verify the specific suffix and package variant against the official datasheet before ordering. Confirm availability status as supply may be restricted. Ensure compatibility with existing PCB footprint and thermal management requirements. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when three-channel unidirectional isolation is required at moderate data speeds. Consider the 16-pin SOIC package constraints for board space. Evaluate power consumption relative to system battery life if applicable. Compare common-mode transient immunity ratings against noise environment requirements.

Part Context

This part belongs to the ADuM231 series of digital isolators designed for general-purpose isolation applications. It complements other variants in the family that offer different channel counts or bidirectional functionality. The series leverages iCoupler technology to replace traditional optocouplers in many designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM231 family. Verify functional equivalence regarding channel count and directionality. Ensure replacement parts meet the same insulation voltage and temperature rating standards.
