ADUM1200WTRZ55-RL7

Overview

The ADUM1200WTRZ55-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features 2/0 channel directionality and operates within a supply voltage range of 2.7V to 5.5V. The device supports data rates up to 25 Mbps with a typical propagation delay of 45 ns. It provides 2500 Vrms isolation voltage and 25 kV/µs common-mode transient immunity. Packaged in an 8-SOIC surface-mount format, it functions across industrial temperature ranges.

Feature Summary

• Dual-channel unidirectional digital isolation using proprietary iCoupler magnetic coupling technology
• High-speed signal transmission capability supporting data rates up to 25 Mbps
• Robust noise immunity characterized by high common-mode transient rejection capabilities

Applications

• Industrial communication bus isolation
• Medical equipment signal isolation
• Power management system interfaces

Procurement Notes

Verify the specific suffix '55' against official Analog Devices documentation to confirm exact electrical or packaging specifications. Ensure compatibility with existing PCB footprints for the 8-SOIC package. Confirm RoHS compliance status through current manufacturer datasheets before integration into production designs.

Selection Notes

Select this component for applications requiring bidirectional data flow separation where only one direction is active. Consider the 25 Mbps speed limit when designing for high-frequency signals. Evaluate the 8-SOIC package constraints against available board space and thermal requirements for the target environment.

Part Context

This part belongs to the ADUM1200 series of digital isolators. It shares core architectural similarities with other variants like the ADUM1200ARZ but differs in specific suffix designations that may indicate automotive qualification or reel packaging variations. The series is known for replacing traditional optocouplers in modern interface designs.

Replacement Considerations

Official substitutes include ADUM1200ARZ and ADUM1200CRZ. Verify pinout compatibility and electrical parameter alignment before substitution.
