ADUM5401WXRWZ

Overview

The ADUM5401WXRWZ is a quad-channel digital isolator featuring an integrated isoPower isolated DC-DC converter. It utilizes iCoupler technology to provide four independent isolation channels with data rates up to 25 Mbps. The device offers a breakdown voltage of 2500 Vrms and a common-mode transient immunity of 25 kV/µs. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum propagation delay of 60 ns. The component is housed in a 16-SOIC package.

Feature Summary

• Integrated isoPower isolated DC-DC converter providing up to 500 mW output power
• Four independent unidirectional signal isolation channels
• High common-mode transient immunity exceeding 25 kV/µs

Applications

• RS-232, RS-422, and RS-485 transceiver isolation
• Industrial fieldbus isolation
• Isolated sensor interfaces
• Industrial PLC systems

Procurement Notes

Verify the current manufacturing status before procurement as this specific part number may be obsolete or discontinued. Confirm availability of valid replacement components such as the ADUM5401WCRWZ if direct sourcing is unavailable. Ensure that any substitute parts match the required pinout, thermal characteristics, and electrical specifications for your specific application design.

Selection Notes

Select this component when a compact solution requiring both signal isolation and isolated power generation is necessary. It eliminates the need for separate isolated DC-DC converters in low-power designs. Consider the 16-SOIC package constraints and ensure PCB layout adheres to high-frequency switching emission standards specified in application notes like AN-0971.

Part Context

This device belongs to the ADuM54xx series of digital isolators from Analog Devices. It leverages proprietary iCoupler chip-scale transformer technology to integrate magnetic coupling elements directly into the semiconductor process. This approach allows for small form factors while maintaining high reliability and safety certifications for industrial applications.
