ADUM341E0WBRWZ-RL

Overview

The ADUM341E0WBRWZ-RL is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler technology with integrated CMOS and monolithic air-core transformer capabilities. It features four unidirectional data channels in a 16-SOIC package, supporting a maximum data rate of 150 Mb/s at 5V operation. The device provides an insulation voltage of 5700 Vrms and withstands an enhanced surge isolation voltage of 10000 V peak. It operates on supply voltages ranging from 2.25 V to 5.5 V, with a typical propagation delay of 6.2 ns and a maximum of 10 ns. The unit is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates high-speed CMOS logic with back-to-back monolithic air-core transformer technology for robust magnetic coupling isolation.
• Provides independent data channels with fault-safe low output configuration for reliable signal transmission across the isolation barrier.
• Delivers high common-mode transient immunity to suppress radiated and conducted noise effectively.
• Supports flexible voltage translation between input and output sides within the 2.25 V to 5.5 V operating range.

Applications

• Serial Peripheral Interface (SPI) isolation
• Data converter isolation
• RS-485 and Controller Area Network (CAN/CAN FD) isolation
• Industrial fieldbus isolation
• PWM controller signal isolation

Procurement Notes

Verify the specific suffix 'E0' indicates the fault-safe low output configuration when sourcing replacements. Confirm that the 'W' designation corresponds to the wide SOIC-16 package dimensions required by the PCB layout. Ensure the component meets AEC-Q100 qualification requirements if deployed in automotive environments. Check for moisture sensitivity labeling as the device is humidity-sensitive. Validate that the ordering part number matches the exact channel count and directionality needed for the circuit design.

Selection Notes

Select this component for designs requiring high-speed data rates up to 150 Mb/s with strong noise immunity. The fault-safe low feature ensures defined states during power-up or fault conditions. Consider the 5700 Vrms insulation rating for safety-critical applications. The wide SOIC package facilitates easier surface-mount assembly compared to narrower variants. Verify thermal performance requirements against the specified operating temperature range of -40°C to +125°C.

Part Context

This part belongs to the ADuM340E/ADuM341E/ADuM342E family of quad-channel digital isolators. The E0 variant specifically denotes the fault-safe low output option, distinguishing it from other configurations like E1 (fault-safe high). It shares the same core iCoupler architecture and pinout structure as its siblings but differs in default output state behavior. The family is designed to replace traditional optocouplers in high-performance industrial and automotive systems.

FAQ

What is the difference between the ADUM341E0 and ADUM341E1 variants?

The primary difference lies in the fault-safe output configuration. The E0 variant defaults to a low output state during fault conditions, while the E1 variant defaults to a high output state.

Does the ADUM341E0WBRWZ-RL support bidirectional communication?

No, this specific model features unidirectional data channels. For bidirectional applications, a different configuration such as the ADUM340 series would be required.
