ADUM3400WARWZ-RL

Overview

The ADUM3400WARWZ-RL is a four-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device features bidirectional signal transmission with a propagation delay of 32 ns and a common-mode transient immunity of 25 kV/µs. It provides 2500 Vrms isolation voltage and is housed in a 16-pin SOIC package. The component is qualified under AEC-Q100 standards for automotive applications and functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Four independent bidirectional channels providing high-speed digital signal isolation
• Integrated iCoupler magnetic coupling technology eliminates the need for external transformers
• High common-mode transient immunity ensures reliable operation in electrically noisy environments
• AEC-Q100 qualification supports deployment in automotive electronic systems

Applications

• Automotive gate driver circuits
• Industrial fieldbus isolation
• Isolated sensor interfaces
• Power supply bias and control loops

Procurement Notes

Verify the specific suffix WARWZ against official Analog Devices documentation to confirm package dimensions and tape-and-reel specifications. Confirm current availability status as distribution listings may indicate limited stock or discontinuation. Ensure compliance with RoHS directives and check for any recent product change notices affecting manufacturing sites or materials before finalizing procurement orders.

Selection Notes

Select this component when four isolated bidirectional channels are required within a compact surface-mount footprint. The 90 Mb/s data rate suits moderate-speed communication protocols. Verify that the 2.7 V to 5.5 V supply range aligns with the system's logic levels. Consider the 32 ns propagation delay for timing-critical designs and ensure the thermal performance meets the requirements for the intended operating temperature environment.

Part Context

This part belongs to the ADUM3400 series of iCoupler digital isolators. It shares the same core architecture and channel count as variants like the ADUM3400CRWZ-RL, differing primarily in the industrial temperature rating and packaging configuration. The series represents a transition from older optocoupler technologies to chip-scale magnetic isolation solutions.

Replacement Considerations

The ADUM3400CRWZ-RL is a documented alternative within the same family. Verify if the commercial temperature grade of the CRWZ variant satisfies the application requirements, as the WARWZ offers extended industrial temperature capabilities.
