ADUM3401WARWZ-RL

Overview

The ADUM3401WARWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates on a single 2.7 V to 5.5 V supply and supports bidirectional data transmission at rates up to 90 Mb/s. The device features four independent channels with two transmitters and two receivers, housed in a 16-pin SOIC package. Key electrical specifications include a propagation delay of 32 ns, an operating supply current of 136 mA, and an isolation voltage rating of 2500 Vrms. It is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates four independent bidirectional digital isolators using chip-level transformer technology
• Provides high-speed signal transmission with low propagation delay characteristics
• Includes integrated DC-DC converter functionality for isolated power generation
• Meets automotive reliability requirements through AEC-Q100 qualification

Applications

• Automotive electronic control units requiring isolated communication
• Industrial automation systems with high noise immunity needs
• Medical equipment requiring reinforced electrical isolation
• Power electronics interfaces for gate drive and sensing

Procurement Notes

Verify the specific suffix WARWZ to confirm the wide-body SOIC-16 package and reel packaging format. Confirm AEC-Q100 automotive qualification status matches project requirements. Check current availability as distribution may be limited or subject to factory special orders. Ensure PCB layout guidelines for the integrated DC-DC converter are followed to meet emission standards.

Selection Notes

Select this component when four isolated bidirectional channels are required within a single package. The integrated isoPower feature eliminates the need for external isolated DC-DC converters, reducing board space. Choose this part over non-integrated variants if power consumption allows for the higher supply current associated with the internal converter. Verify that the 90 Mb/s data rate meets system timing constraints.

Part Context

This part belongs to the ADUM3401 series of quad-channel digital isolators. It differs from the ADUM3401WBRWZ-RL primarily by its wider body package (SOIC-16 W) which offers increased creepage distance. It shares the same core functionality and electrical performance as other members of the family but provides enhanced isolation safety margins due to the physical package dimensions.

Replacement Considerations

ADUM3401WBRWZ-RL: Same electrical performance but in a standard SOIC-16 package with reduced creepage distance.
