ADUM341E1WBRWZ-RL

Overview

The ADUM341E1WBRWZ-RL is a four-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features a 5700Vrms isolation voltage 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, ensuring compatibility with low-voltage systems. It includes a fault-safe high output configuration and meets AEC-Q100 automotive standards. Packaged in a 16-SOIC format, it provides robust performance for industrial applications.

Feature Summary

• Integrates four independent data channels with high common-mode transient immunity.
• Provides enhanced surge isolation voltage ratings for reliable operation in noisy environments.
• Supports bidirectional level translation between 2.25V and 5.5V power domains.

Applications

• Isolation for Controller Area Network (CAN) and CAN FD interfaces
• Signal isolation for RS-485 communication buses
• Digital isolation for Serial Peripheral Interface (SPI) connections

Procurement Notes

Verify the specific suffix 'WBRWZ-RL' against official datasheets to confirm package dimensions and reel specifications. Ensure the E1 designation matches the required fault-safe logic state for your circuit design. Cross-reference the manufacturing date code to ensure compliance with current RoHS directives and automotive quality standards before finalizing procurement orders.

Selection Notes

Select this component when high channel count isolation is required within a compact footprint. The 150Mbps data rate suits high-speed serial communications, while the 5700Vrms rating offers significant safety margins. Consider the fault-safe feature if input signal loss must result in a defined high output state to maintain system safety during failure conditions.

Part Context

This part belongs to the ADuM34xE series of quad-channel digital isolators. It shares the same physical package and core magnetic coupling architecture as variants like the ADUM340E and ADUM342E. The primary distinction lies in the internal logic configuration, specifically the fault-safe output behavior determined by the 'E1' suffix.

Replacement Considerations

Public confirmed substitute part numbers include ADUM341E0WBRWZ and ADUM341E1BRWZ. Verify that alternative options match the required insulation voltage and data rate specifications. Confirm that any replacement maintains the necessary AEC-Q100 qualification if used in automotive applications.
