ADUM6404CRWZ-RL

Overview

The ADUM6404CRWZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated DC/DC converter for power isolation. It operates within a 3 V to 5.5 V supply range and supports data rates up to 25 Mb/s. The device provides 5000 Vrms insulation voltage with magnetic coupling technology. Key electrical parameters include a propagation delay of 60 ns, typical rise/fall times of 2.5 ns, and a maximum power dissipation of 400 mW. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates a high-efficiency DC/DC converter to provide isolated power on the secondary side, eliminating external transformer requirements.
• Utilizes iCoupler magnetic coupling technology to achieve robust signal isolation without optical or capacitive components.
• Offers four independent unidirectional channels for simultaneous data transmission across the isolation barrier.

Applications

• Industrial automation systems requiring galvanic isolation between control and sensor domains.
• Medical equipment interfaces needing high-voltage isolation for patient safety compliance.
• Power electronics monitoring circuits where noise immunity and compact form factors are critical.

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design accounts for the ISOPwr topology which requires specific decoupling capacitor placement near the package pins for stable operation.

Selection Notes

Select this component when both signal isolation and isolated power delivery are required in a single package. Compare against the ADUM5404 series if lower insulation voltage (2500 Vrms) suffices for the application. Consider the ADUM6400 series for non-reel packaging options if inventory flexibility is needed.

Part Context

This part belongs to the ADUM6400 family of IsoPower digital isolators. It shares architectural similarities with the ADUM5404 but offers higher insulation ratings. The SOIC-16 package allows for surface-mount installation, supporting automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

The ADUM6400CRWZ is a related variant within the same family offering identical electrical specifications. Verify pinout compatibility and thermal performance before substituting. Check datasheet revisions for any changes in recommended operating conditions.
