ADUM341E0WBRWZ

Overview

The ADUM341E0WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology. It features four independent data channels with a unidirectional 3:1 configuration (three forward, one reverse). The device supports data rates up to 150 Mb/s and offers a high common-mode transient immunity of 100 kV/µs. It operates on supply voltages ranging from 2.25 V to 5.5 V and provides an insulation voltage of 10,000 Vrms. Packaged in a 16-pin SOIC, it is AEC-Q100 qualified for automotive applications.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air-core transformer technology.
• Provides robust noise immunity with high common-mode transient rejection capabilities.
• Supports flexible logic level translation between 2.25 V and 5.5 V domains.
• Designed for high-reliability environments with extended temperature range operation.

Applications

• Industrial fieldbus isolation
• CAN and CAN FD interface isolation
• RS-485 communication link isolation
• PWM controller signal isolation

Procurement Notes

Verify the specific suffix against official documentation to confirm channel directionality and fault-safe states. Ensure the ordering part number matches the required package variant and reel specifications. Confirm AEC-Q100 qualification status if automotive compliance is mandatory for the target application design.

Selection Notes

Select this component when high-speed bidirectional or asymmetric data transfer is required across isolated boundaries. The 3:1 channel configuration suits applications needing multiple outputs from a single source. Consider the 10,000 Vrms insulation rating for high-voltage industrial systems requiring enhanced safety margins.

Part Context

This part belongs to the ADuM34xE series of quad digital isolators. It shares the same core iCoupler architecture as the ADUM340E and ADUM342E models but differs in channel configuration and fault-safe output states. The series is designed for general-purpose multi-channel isolation needs.

Replacement Considerations
