ADUM5404ARWZ

Overview

The ADUM5404ARWZ is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower DC-to-DC converter. It provides 2500 Vrms isolation via magnetic coupling in a 16-pin SOIC package. The device supports data rates up to 25 Mb/s with a propagation delay of 60 ns. Operating voltage ranges from 3 V to 5.5 V, with a typical supply current of 19 mA. It functions within a temperature range of -40°C to +105°C and offers 25 kV/µs common-mode transient immunity.

Feature Summary

• Integrates an isoPower isolated DC-to-DC converter for simplified power delivery across the isolation barrier
• Provides four independent bidirectional or unidirectional logic channels with high-speed signal transmission
• Utilizes silicon dioxide (SiO2) insulation technology for reliable magnetic coupling isolation

Applications

• Industrial automation systems requiring galvanic isolation between control and sensor domains
• Medical equipment needing safety-certified isolation for patient-connected circuits
• Power electronics interfaces for monitoring and controlling high-voltage rails

Procurement Notes

Verify the specific suffix 'ARWZ' matches the required temperature grade and package width. Confirm that the 'RL' variant indicates reel packaging if applicable to your assembly process. Ensure compatibility with the 16-SOIC footprint dimensions. Check for moisture sensitivity level requirements during storage and handling procedures before soldering.

Selection Notes

Select this component when four isolated channels are necessary alongside integrated power conversion. Compare against single-channel isolators if fewer signals require isolation. Consider the 2500 Vrms rating against system insulation requirements. Evaluate the 19 mA supply current impact on overall thermal management and efficiency constraints in the design.

Part Context

This part belongs to the ADuM540x family of quad-channel digital isolators. It shares architectural similarities with the ADUM5401, ADUM5402, and ADUM5403, differing primarily in channel configuration and pinout assignments. The series emphasizes compact integration of isolation and power management functions.

Replacement Considerations

Direct substitutes include other members of the ADuM540x family such as the ADUM5401, ADUM5402, or ADUM5403, provided pin compatibility and channel requirements align. Verify functional equivalence regarding isolation voltage and data rate specifications before substitution.
