ADUM5400ARWZ

Overview

The ADUM5400ARWZ is a quad-channel digital isolator from Analog Devices Inc., featuring integrated isoPower isolation DC-DC converters. It provides four independent channels with a data rate of 1 Mbps and a common-mode transient immunity (CMTI) of 25 kV/µs. The device operates within a supply voltage range of 3 V to 5.5 V on the input side and 4.5 V to 5.5 V on the output side. It utilizes magnetic coupling technology for signal transmission across the isolation barrier. The component is housed in a 16-pin SOIC package with a width of 7.50 mm, designed for surface-mount installation.

Feature Summary

• Integrates isolated DC-DC power converters alongside signal isolation channels
• Utilizes iCoupler magnetic coupling technology for robust signal transmission
• Provides high common-mode transient immunity for noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with isolated communication interfaces

Procurement Notes

Verify the specific suffix ARWZ against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before procurement. Check current availability status as distribution may vary by region. Confirm RoHS compliance and moisture sensitivity level if required by assembly processes.

Selection Notes

Select this component when both signal isolation and isolated power delivery are required in a single package. It is suitable for designs needing four isolated channels with integrated power conversion. Consider the 1 Mbps data rate and 25 kV/µs CMTI specifications against application needs. Evaluate the 16-SOIC footprint constraints during PCB layout planning.
