ADUM5400CRWZ

Overview

The ADUM5400CRWZ is a quad-channel digital isolator from Analog Devices, featuring isoPower integrated isolated DC-to-DC conversion. It provides four data channels with unidirectional signal transmission at a maximum data rate of 25 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and offers an isolation voltage of 2500 Vrms using magnetic coupling technology. Key electrical parameters include a propagation delay of 60 ns, typical rise and fall times of 2.5 ns, and a power dissipation rating of 500 mW. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across the isolation barrier
• Provides four independent high-speed digital channels for complex system interfacing
• Utilizes magnetic coupling technology to ensure robust signal integrity and galvanic isolation

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing high-voltage isolation for patient safety
• Automotive electronics utilizing CAN or LIN bus networks
• Test and measurement instruments requiring precise signal separation

Procurement Notes

Verify the specific suffix (e.g., CRWZ) against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with your board layout regarding the SOIC-16 footprint. Confirm that the integrated DC/DC converter requirements align with your system's power budget and noise sensitivity constraints before finalizing procurement.

Selection Notes

Select this component when a quad-channel isolator with integrated power is required to reduce external component count. Compare against non-isolated power variants if external power supplies are preferred. Consider the 2500 Vrms isolation rating against system voltage requirements. Evaluate the 60 ns propagation delay against timing-critical applications in your design.

Part Context

This part belongs to the ADuM5400 family of digital isolators, which combines high-speed data isolation with integrated power conversion. It is designed to replace traditional optocoupler-based solutions in modern electronic designs. The series supports various interface protocols and is widely used in industrial and automotive sectors where reliable isolation is critical.

Replacement Considerations

Check for direct pin-compatible replacements within the ADuM5400 series. Verify if alternative packages such as WSOIC are available for different mounting needs. Ensure any substitute maintains the same isolation voltage and data rate specifications.
