ADUM226N0WBRIZ

Overview

The ADUM226N0WBRIZ is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features one reverse channel and supports data rates up to 150 Mb/s with a propagation delay of 7.2 ns. The device operates within a supply voltage range of 3 V to 5.5 V and provides robust insulation of 5000 Vrms. It is housed in an SOIC-8 package and is qualified under AEC-Q100 standards, ensuring reliability across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via magnetic coupling technology
• Supports bidirectional communication with two forward channels and one reverse channel
• Meets automotive qualification standards for high-reliability applications

Applications

• Automotive electronic systems requiring certified isolation
• Industrial automation control circuits
• Motor drive interface protection

Procurement Notes

Verify the specific suffix 'WBRIZ' against the manufacturer's official datasheet to confirm pinout configuration and RoHS compliance status. Ensure that the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the AEC-Q100 qualification meets the specific grade requirements of your target application before finalizing procurement.

Selection Notes

Select this component when bidirectional signal isolation is required alongside unidirectional channels. The 5000 Vrms insulation rating suits high-voltage separation needs. Consider the 150 Mb/s data rate limit for bandwidth requirements. The wide operating temperature range makes it suitable for harsh environments where standard commercial parts may fail.

Part Context

This part belongs to the ADUM226N series of digital isolators. It shares the core magnetic coupling architecture with other members of the family but differs in channel count and directionality. The series is designed to replace traditional optocouplers in modern designs, offering higher speed and better consistency.

Replacement Considerations

Check for ADUM226N variants with different packaging or channel configurations. Verify if alternative models offer higher data rates or different insulation voltages while maintaining the same SOIC-8 footprint.
