ADUM341E1BRWZ-RL

Overview

The ADUM341E1BRWZ-RL is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four independent data channels with a 3:1 input-to-output configuration (three unidirectional inputs to one output). The device supports data rates up to 150Mbps and offers a high isolation voltage of 5700Vrms. It operates on supply voltages ranging from 2.25V to 5.5V and includes AEC-Q100 automotive qualification. Key electrical parameters include a maximum propagation delay of 10ns, typical rise/fall times of 2.5ns, and a minimum common-mode transient immunity of 100kV/µs.

Feature Summary

• High-speed data transmission capability supporting up to 150Mbps for efficient signal integrity in demanding applications.
• Robust magnetic coupling isolation providing enhanced noise immunity and reliable performance in electrically noisy environments.
• Automotive-grade reliability certified under AEC-Q100 standards for operation in harsh industrial and vehicle conditions.

Applications

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

Procurement Notes

Verify the specific suffix 'E1' indicates the fault-safe high logic level output state required for the design. Confirm the '-RL' suffix denotes reel packaging suitable for automated surface-mount assembly processes. Ensure compatibility with the target system's voltage levels and thermal requirements before finalizing the component selection.

Selection Notes

Select this component when high-speed bidirectional or unidirectional isolation is needed with strict timing constraints. The 3:1 channel configuration is optimal for controlling multiple outputs from fewer control lines. Consider the 5700Vrms isolation rating for safety-critical applications requiring robust barrier protection between low-voltage control circuits and high-voltage power stages.

Part Context

This part belongs to the ADuM341E series of quad-channel digital isolators. It shares the same core architecture as the ADUM341E0 variant but differs in output logic state defaults. The E1 designation specifies a fault-safe high output, whereas other variants may default to low. It is designed for applications requiring high channel density and fast switching speeds within a compact SOIC package.

Replacement Considerations

ADUM341E0WBRWZ and ADUM341E1WBRWZ are parameter-equivalent alternatives. Verify that the replacement matches the required fault-safe output state (E1 vs E0) and packaging format (reel vs tube) to ensure seamless integration without circuit modification.
