ADUM5401WCRWZ-1RL

Overview

The ADUM5401WCRWZ-1RL is a quad-channel digital isolator featuring an integrated isoPower DC-DC converter. It provides four independent isolation channels with a data rate of 25 Mbps and a propagation delay of 60 ns. The device supports a supply voltage range of 3 V to 5.5 V and offers an insulation voltage of 2500 Vrms. It operates within a temperature range of -40°C to +105°C, utilizes magnetic coupling technology, and is housed in a 16-SOIC package.

Feature Summary

• Integrates an isolated DC-DC converter for power delivery across the isolation barrier
• Provides four unidirectional signal channels for data transmission
• Utilizes iCoupler magnetic coupling technology for compact design

Applications

• Isolated battery monitoring systems
• Industrial PLC communication interfaces
• Sensor interface isolation

Procurement Notes

Verify the specific suffix '1' against official Analog Devices documentation to confirm it denotes AEC-Q100 automotive qualification rather than a functional deviation. Ensure the '-RL' designation matches the required tape-and-reel packaging format for your assembly process. Cross-reference the datasheet revision date to validate current parameter specifications.

Selection Notes

Select this component when a single IC must provide both signal isolation and isolated power generation. It eliminates the need for external isolated converters. Verify that the 500 mW output capability meets the load requirements. Confirm compatibility with the 3 V to 5.5 V input supply range and check if the 25 Mbps speed suffices for the application.

Part Context

This part belongs to the ADUM5401 series of quad-channel isolators. It differs from standard variants by including the isoPower feature. The series uses chip-level transformer technology. It replaces older discrete isolation solutions. The W variant indicates wide operating temperature range.

Replacement Considerations

ADUM5401WCRWZ is a tube-packaged equivalent. ADUM5401CRWZ lacks the integrated DC-DC converter. ADUM5401ARWZ-RL is an automotive-grade alternative without the isoPower feature.
