Procurement Notes

Verify the specific suffix BRSZ to confirm the SSOP-20 package and tape-and-reel or tube availability depending on the distributor. Confirm RoHS compliance status as manufacturing processes may update. Check for any recent Product Change Notifications that might affect pinout or material composition before finalizing procurement orders.

Selection Notes

Select this component when dual-channel LVDS isolation is required at speeds up to 2.5 Gbps. Ensure the system design accommodates the specified supply voltage ranges and thermal dissipation requirements. Compare against other ADN46xx series parts if channel count or isolation voltage needs differ. Verify package compatibility with PCB footprint constraints during the initial design phase.

Part Context

This part belongs to the ADN462x family of high-speed digital isolators from Analog Devices. These devices utilize proprietary isolation technology to provide robust performance in electrically noisy environments. The family includes variants with different channel counts and packaging options to suit various interface requirements.

Replacement Considerations

Direct replacements include other ADN4621 variants such as ADN4621BRIZ for different packaging. Cross-family alternatives like ADN4651 offer lower data rates but similar isolation characteristics. Always verify pin-to-pin compatibility and electrical specifications before substituting.
