• PWM controller signal isolation
• General-purpose multi-channel isolation

Procurement Notes

Verify the specific suffix (e.g., IZ vs RL) to confirm packaging type, as tube and reel variants share identical electrical specifications. Ensure compatibility with the required isolation voltage ratings and temperature ranges for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when high-speed data transmission exceeding standard optocoupler limits is required alongside robust electromagnetic interference rejection. The integrated magnetic coupling technology eliminates LED degradation risks associated with traditional optical isolation solutions.

Part Context

This part belongs to the ADuM320N/ADuM321N series of dual-channel digital isolators. These devices integrate CMOS circuitry with monolithic air-core transformer technology to provide reliable signal isolation across electrical barriers without using light-emitting diodes or photodiodes.

Replacement Considerations

Cross-reference with ADUM3210ARZ-RL7 for lower speed requirements. Verify pinout compatibility and isolation voltage ratings against existing designs when substituting.
