ADUM226N0BRIZ

Overview

The ADUM226N0BRIZ is a robust dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two forward channels and one reverse channel within an 8-pin SOIC package. The device supports data rates up to 150 Mb/s with a propagation delay of 7.2 ns. It operates on a supply voltage range of 3 V to 5.5 V and draws typical supply currents of 5.4 mA or 5.9 mA depending on the channel configuration. The isolator provides 5000 Vrms isolation voltage and withstands common-mode transients of 75 kV/µs. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for high-speed signal transmission without optical components.
• Provides robust 5000 Vrms isolation capability with high common-mode transient immunity of 75 kV/µs.
• Integrates two forward channels and one reverse channel in a compact surface-mount package.
• Meets AEC-Q100 qualification standards for automotive reliability and extended temperature operation.

Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing reinforced isolation barriers
• Power conversion circuits with isolated gate drive requirements

Procurement Notes

Verify the specific suffix '0' indicates the 3V minimum supply variant distinct from other family members. Confirm AEC-Q100 automotive qualification status if required for your design. Check current availability as distribution may be limited. Ensure the SOIC-8 package width matches your PCB footprint constraints. Validate RoHS compliance documentation prior to final procurement decisions.

Selection Notes

Select this component when bidirectional communication is needed alongside standard forward isolation. The inclusion of a reverse channel simplifies designs requiring acknowledgment signals or half-duplex protocols. Compare power consumption against single-direction isolators if reverse channel usage is unnecessary. Ensure the 150 Mbps speed meets system timing requirements. Verify that the 8.3mm creepage distance satisfies safety clearance regulations for your application voltage.

Part Context

This part belongs to the ADuM226N series of digital isolators designed for general-purpose isolation tasks. It complements unidirectional variants by offering integrated return path capabilities. The series leverages silicon dioxide insulation layers for long-term stability. It serves as a drop-in replacement for older optocoupler designs in space-constrained environments.

Replacement Considerations

Consider ADUM226N1BRIZ for similar functionality with a lower 1.7V minimum supply voltage requirement. Evaluate ADUM226N0WBRIZ-RL if reel packaging is preferred over tube packaging for automated assembly processes. Ensure pinout compatibility remains identical when substituting between these variants.
