Procurement Notes

Verify the specific suffix (E1) against official Analog Devices documentation to confirm pinout and electrical characteristics match project requirements. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing procurement decisions.

Selection Notes

Select this component when high-speed bidirectional or unidirectional data transfer requires galvanic isolation in space-constrained designs. Consider the 16-SOIC package dimensions and the specific 2:1 channel topology relative to system interface needs.

Part Context

This part belongs to the ADuM23x series of triple-channel digital isolators. It shares architectural similarities with the ADUM230 series but offers distinct channel configurations and performance metrics tailored for general-purpose isolation tasks requiring robust noise immunity.

Replacement Considerations

Cross-reference with ADUM231D0BRIZ for similar specifications. Verify that any substitute maintains the required 5000Vrms isolation rating and 150Mbps data rate capabilities.
