ADUM4400CRWZ

Overview

The ADUM4400CRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation voltage with a data rate of 90 Mbps and 25 kV/µs common-mode transient immunity. The device operates on a 3V to 5.5V supply, features unidirectional channels in a 16-SOIC package, and supports an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS and monolithic air core transformer technology for superior performance over optical couplers
• Provides enhanced system-level ESD performance compliant with IEC 61000-4-x standards
• Offers low power operation with precise timing characteristics and output enable functionality

Applications

• General high-voltage multi-channel isolation
• Medical equipment signal isolation
• Power supply control loops
• Motor drive gate interfaces

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging configuration and compliance status. Ensure the component matches the required isolation voltage and channel count for the target application design specifications.

Selection Notes

Select this component when high-speed bidirectional communication is not required, as it supports only unidirectional data flow. Consider the 16-SOIC footprint constraints and verify that the 5000 Vrms isolation rating meets the safety requirements of the isolated boundary.

Part Context

Part of the ADuM440x series within the Analog Devices iCoupler family. This series combines magnetic coupling with CMOS logic to replace traditional optocouplers in applications demanding higher reliability, lower power consumption, and better channel-to-channel matching.

Replacement Considerations

Check ADUM4401 or ADUM4402 for different channel configurations. Verify ADUM4400CRWZ-RL if reel packaging is preferred over tube.
