ADUM4401WBRWZ

Overview

The ADUM4401WBRWZ is a quad-channel digital isolator from Analog Devices, utilizing proprietary cmos2is technology for magnetic coupling. It provides four independent isolation channels with unidirectional data transmission capability. The device supports a data rate of 90 Mb/s and operates within a supply voltage range of 2.7 V to 5.5 V. It features an insulation rating of 5000 Vrms and includes enhanced ESD protection. The component is housed in a SOIC-16 package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates four independent digital isolation channels using magnetic coupling technology
• Provides enhanced electrostatic discharge (ESD) protection capabilities
• Supports high-speed data transmission at rates up to 90 Mb/s
• Meets AEC-Q100 qualification standards for automotive reliability

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial systems needing robust galvanic isolation between circuits
• Power electronics applications involving high-voltage switching isolation
• Medical equipment requiring safe patient isolation barriers

Procurement Notes

Verify the specific suffix WBRWZ against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compliance with RoHS directives and check for any regional distribution restrictions or limited availability notices before finalizing procurement plans.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required at 90 Mb/s speeds. Consider the 5000 Vrms insulation rating for high-noise environments. Verify that the SOIC-16 footprint fits the design constraints and that AEC-Q100 qualification meets automotive project requirements.

Part Context

This part belongs to the ADUM4401 series of quad-channel digital isolators. It shares the core cmos2is magnetic coupling architecture with other members of the family but differs in channel count and speed specifications compared to single or dual-channel variants like the ADUM1401.
