ADUM226N0WBRIZ-RL

Overview

The ADUM226N0WBRIZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two unidirectional channels and one reverse channel within an 8-SOIC package. The device supports data rates up to 150 Mb/s with a propagation delay of 7.2 ns. It offers robust isolation with 5000 Vrms insulation voltage and 8.3 mm creepage distance. Operating on a supply voltage range of 1.7V to 5.5V, it draws 5.9 mA of working power supply current. The component is AEC-Q100 qualified for automotive applications.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers
• Provides high common-mode transient immunity to protect against noise in harsh environments
• Includes integrated DC-DC converter capability for isolated power generation
• Meets automotive reliability standards through AEC-Q100 qualification

Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing reinforced safety isolation
• Power metering systems with high-voltage separation requirements

Procurement Notes

Verify the specific suffix WBRIZ corresponds to the reel packaging format when ordering. Confirm that the AEC-Q100 qualification status meets your project's automotive grade requirements. Ensure the SOIC-8 footprint matches your PCB layout constraints. Check for any RoHS compliance documentation updates prior to final procurement approval.

Selection Notes

Select this component when bidirectional communication is not required for all channels, as it provides two forward and one reverse path. Consider the 150 Mb/s speed limit for high-speed interface compatibility. Evaluate the 5.9 mA current consumption against battery-operated system constraints. Verify that the 5000 Vrms isolation rating satisfies the safety regulations of the target application domain.

Part Context

This part belongs to the ADUM226N series of digital isolators designed for general-purpose isolation tasks. It shares the same core iCoupler architecture with other variants in the family but differs in channel configuration and packaging options. The series is known for replacing traditional transformer and optocoupler solutions in compact designs.

Replacement Considerations

Direct substitutes include ADUM226N1BRIZ for tube packaging or ADUM226N0WBRIZ for non-reel tape formats. Cross-reference with ADUM225N variants if different channel configurations are acceptable.
