Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the manufacturer part number matches ADUM321N0BRZ-RL7 exactly to ensure correct channel count and speed specifications. Check current availability status as supply may be limited. Ensure compatibility with your board's SOIC-8 footprint and voltage requirements before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation with high speed (150Mbps) and high CMTI (100kV/µs) is required. It is suitable for applications demanding wide operating temperatures (-40°C to 125°C). Compare against standard 10Mb/s variants if higher throughput is necessary. Ensure the 2.25V to 5.5V supply range aligns with system power rails.

Part Context

This part belongs to the ADuM321N series of dual digital isolators. It shares the core iCoupler technology family but differs in speed and insulation ratings from other variants like the ADUM3211 or ADUM3210. The 'N' designation typically denotes specific performance characteristics within the broader ADUM32xx product line.
