ADUM340E1BRWZ-RL

Overview

The ADUM340E1BRWZ-RL is a quad-channel digital isolator utilizing iCoupler technology, featuring capacitive coupling for signal transmission. It provides an isolation voltage of 5700Vrms and supports data rates up to 150Mbps with a maximum propagation delay of 10ns. The device operates on supply voltages ranging from 2.25V to 5.5V and offers a common-mode transient immunity of 100kV/µs. Packaged in a 16-SOIC format, it is designed for high-speed applications requiring robust noise rejection.

Feature Summary

• Integrates four independent unidirectional data channels within a single package.
• Provides enhanced safety compliance through UL certification and VDE qualification.
• Delivers high common-mode transient immunity for reliable operation in noisy environments.
• Supports flexible logic levels across the 2.25V to 5.5V supply range.

Applications

• Industrial fieldbus isolation
• CAN FD communication interfaces
• RS-485 data line isolation
• SPI interface isolation

Procurement Notes

Verify the specific suffix 'E1' to confirm the fault-safe high output configuration and ensure compatibility with the required 5700Vrms isolation rating. Confirm that the 16-SOIC package dimensions align with the target PCB layout constraints. Cross-reference the AEC-Q101 automotive qualification status if the application demands strict reliability standards beyond standard industrial specifications.

Selection Notes

Select this component when high-speed data transfer exceeding 100Mbps is required alongside stringent isolation voltage requirements. The unidirectional channel architecture suits applications where signal flow is strictly one-way. Ensure the system design accommodates the specified 2.25V to 5.5V operating range for both sides of the isolation barrier without external level shifting.

Part Context

This part belongs to the ADuM34xE family of quad digital isolators from Analog Devices. The series leverages monolithic air-core transformer technology to achieve galvanic isolation. The E1 variant specifically denotes the fault-safe high output state, distinguishing it from other configurations within the broader ADUM340 product line.
