ADUM340E0WBRWZ-RL

Overview

The ADUM340E0WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology with complementary metal-oxide-semiconductor and monolithic transformer construction. It provides 5700 Vrms isolation voltage and supports data rates up to 150 Mbps. The device operates on supply voltages between 2.25 V and 5.5 V, featuring a maximum propagation delay of 10 ns and pulse width distortion under 3 ns. It includes AEC-Q100 qualification for automotive applications and offers fault-safe low output configuration.

Feature Summary

• High common-mode transient immunity of 180 kV/µs typical
• Robust noise rejection against radiated and conducted interference
• Independent data channels with flexible input/output configurations
• Integrated magnetic coupling via back-to-back monolithic air-core transformers

Applications

• CAN and CAN FD bus isolation
• RS-485 and RS-422 communication interfaces
• SPI data converter isolation
• Industrial fieldbus systems requiring high-speed galvanic separation

Procurement Notes

Verify the specific suffix WBRWZ-RL against official Analog Devices documentation to confirm package type, temperature grade, and reel specifications. Ensure compatibility with system voltage requirements and isolation standards before integration. Cross-reference part numbers carefully as minor suffix variations may indicate different packaging or regional compliance certifications.

Selection Notes

Select this component when high-speed bidirectional isolation is required for protocols like CAN FD or RS-485. The 5700 Vrms rating suits industrial environments with significant ground potential differences. Consider the fault-safe low feature if signal integrity during power loss is critical. Verify thermal performance at +125°C operation if used in enclosed automotive or industrial enclosures.

Part Context

This part belongs to the ADuM34xE series of quad-channel digital isolators. It shares the core iCoupler architecture with variants offering different channel directions or output states. The E-series designation indicates enhanced performance characteristics including higher speed and robustness compared to standard models.

Replacement Considerations

Direct substitutes include ADUM340E1BRWZ-RL (fault-safe high) and ADUM3402WBRWZ-RL (different speed/isolation profile). Verify pinout compatibility and logic directionality before swapping. Check if alternative packages meet board space constraints.
