Procurement Notes

Verify the specific suffix '35' against official Analog Devices documentation to confirm automotive qualification status and exact parameter tolerances. Ensure the reel packaging format matches system requirements. Cross-reference the datasheet revision date to validate current manufacturing status and any recent design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when high-speed isolation exceeding 1 Mbps is required alongside robust noise immunity. The 16-SOIC package suits space-constrained designs needing multiple isolated channels. Consider the 90 Mb/s data rate capability for high-bandwidth applications. Verify that the 2.7V to 5.5V supply range aligns with the target logic levels on both sides of the isolation barrier.

Part Context

This part belongs to the ADUM1402 family of digital isolators, which are designed to replace traditional optocouplers in many applications. The family leverages CMOS process technology to achieve lower power consumption and higher reliability. The ADUM1402 series provides a scalable solution for various isolation needs within industrial and automotive sectors.

Replacement Considerations

ADUM1402ARW is listed as a discontinued alternative. Check for parameter equivalence regarding channel count and isolation ratings. Verify if newer revisions like ADUM1402WTRWZ offer improved specifications or updated packaging options suitable for direct replacement.
