ADUM341E0WBRQZ

Overview

The ADUM341E0WBRQZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration with three unidirectional forward channels and one reverse channel. The device supports data rates up to 150 Mb/s and operates on supply voltages between 2.25 V and 5.5 V. It provides insulation voltages of 3 kVrms and 5.7 kVrms, with a typical propagation delay of 6.2 ns. Qualified under AEC-Q100 for automotive applications, it functions within a temperature range of -40°C to +125°C and is housed in a QSOP-16 package.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air-core transformer technology for high-speed signal transmission.
• Provides enhanced safety ratings with reinforced insulation capabilities suitable for demanding industrial environments.
• Features fault-safe output options ensuring defined logic states during power loss or signal interruption.
• Delivers high common-mode transient immunity to maintain signal integrity in electrically noisy systems.

Applications

• Isolation for Controller Area Network (CAN) and CAN FD interfaces in automotive systems
• Signal isolation for RS-485 communication buses in industrial automation
• Galvanic isolation for Serial Peripheral Interface (SPI) connections in data acquisition systems

Procurement Notes

Verify the specific suffix QZ indicates automotive qualification and RoHS compliance when sourcing. Confirm the E0 variant corresponds to the required fault-safe logic state for your design. Check current availability status as distribution may be limited. Ensure the QSOP-16 package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a 3:1 directional isolation topology is required for mixed-signal systems. The E0 suffix denotes a specific default output state; verify this matches your system's idle requirements compared to the E1 variant. Consider the 150 Mb/s speed limit against your bus requirements. The AEC-Q100 qualification makes it suitable for harsh automotive environments where standard commercial parts may fail.

Part Context

This part belongs to the ADuM34xE family of quad digital isolators designed for high-reliability applications. The family shares core iCoupler technology but varies in channel directionality and insulation ratings. The ADUM341 series specifically targets applications requiring asymmetric data flow, such as master-slave communication protocols where data moves primarily in one direction.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering alternative manufacturers, as pinouts and electrical characteristics may differ significantly.
