ADUM3401WARWZ

Overview

The ADUM3401WARWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates on a single power supply ranging from 2.7 V to 5.5 V and provides four independent bidirectional data channels within a 16-lead SOIC package. The device supports high-speed data transmission with a maximum rate of 90 Mb/s and features a typical propagation delay of 32 ns. It offers an insulation voltage of 2500 Vrms and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Integrates four independent bidirectional data channels using iCoupler magnetic coupling technology for robust signal isolation.
• Supports high-speed data transmission up to 90 Mb/s with low propagation delay characteristics.
• Operates on a single power supply range of 2.7 V to 5.5 V, ensuring compatibility with various logic levels.
• Meets AEC-Q100 automotive qualification standards for reliability in demanding environments.

Applications

• Isolation of serial peripheral interface (SPI) communication lines
• Signal isolation in industrial fieldbus systems
• Gate driver isolation for power electronics applications

Procurement Notes

Verify the specific suffix 'W' indicates the wide temperature grade and 'RZ' denotes the tape and reel packaging configuration. Confirm that the component meets AEC-Q100 requirements if intended for automotive use. Check current availability status as supply may be restricted or limited. Ensure the ordering part number matches the exact speed grade and package type required for the design.

Selection Notes

Select this component when high-speed bidirectional isolation is required for multiple channels simultaneously. The 90 Mb/s data rate suits applications needing faster throughput than standard 1 Mb/s isolators. The 16-lead SOIC package facilitates surface-mount assembly. Consider the 2500 Vrms insulation rating for safety compliance in high-voltage separation scenarios.

Part Context

This part belongs to the ADUM3401 series of quad-channel digital isolators. It shares the same core architecture and pinout with variants like ADUM3401ARWZ but differs in speed grade and packaging. The series utilizes proprietary iCoupler technology to replace traditional transformer-based isolation solutions.

Replacement Considerations

ADUM3401CRWZ is a confirmed substitute offering identical electrical specifications and functionality in a tube package instead of reel.
