• Employs iCoupler magnetic coupling technology to achieve robust signal isolation without optical or capacitive components.
• Provides bidirectional data transmission across two independent channels with high common-mode transient immunity.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable galvanic isolation
• Medical equipment requiring safety-certified signal isolation

Procurement Notes

Verify the specific suffix 'W' versus 'C' in the part number against official Analog Devices documentation to confirm temperature range and qualification status. Confirm RoHS compliance details directly from the manufacturer's datasheet. Check current availability status as distribution may vary by region. Ensure the reel packaging quantity matches project requirements.

Selection Notes

Select this component when a dual-channel isolator with integrated isolated power is required to simplify board design. It is suitable for applications demanding high CMTI and moderate data rates. Compare performance metrics such as propagation delay and quiescent current against other iCoupler products if lower power consumption or higher speed is needed.
