ADUM3400CRWZ

Overview

The ADUM3400CRWZ is a quad-channel digital isolator utilizing Analog Devices iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an isolation voltage of 2500 Vrms. The device supports data rates up to 90 Mb/s with a maximum propagation delay of 32 ns. It features bidirectional channels, a typical rise/fall time of 3 ns, and a common-mode transient immunity of 25 kV/µs. Operating temperatures span from -40°C to +105°C in a 16-lead SOIC package.

Feature Summary

• Integrates high-speed CMOS circuitry with single-chip air-core transformer technology for signal transmission.
• Provides enhanced system-level electrostatic discharge (ESD) reliability compared to traditional optocouplers.
• Offers bidirectional communication capability across all four isolated channels.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high-voltage interfaces

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel configuration. Ensure compatibility with RoHS3 standards and check for any recent product change notices regarding manufacturing sites or material composition updates before finalizing procurement.

Selection Notes

Select this component when bidirectional data transfer is required alongside robust ESD protection. Compare performance metrics such as propagation delay and power consumption against alternative isolators to ensure suitability for the specific timing constraints and thermal management requirements of the target application design.

Part Context

This part belongs to the ADuM3400 series, which includes variants like the ADUM3401 and ADUM3402. These devices share the same iCoupler architecture but differ in channel directionality configurations. The series represents a general-purpose solution for replacing optocouplers in modern electronic designs.

Replacement Considerations

Direct substitutes include ADUM3401CRWZ and ADUM3402CRWZ. Verify channel directionality requirements, as these variants offer different input/output configurations while maintaining similar electrical characteristics and packaging.
