ADUM1200WSRZ35-RL7

Overview

The ADUM1200WSRZ35-RL7 is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It features 2/0 channel directionality and supports data rates up to 25 Mbps. The device operates on a supply voltage range of 2.7 V to 5.5 V with a typical quiescent current of 4.3 mA per channel. It provides an isolation voltage of 2500 Vrms and a common-mode transient immunity of 25 kV/µs. Packaged in an 8-SOIC, it meets AEC-Q100 automotive qualification standards and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Implements iCoupler magnetic coupling technology for high-speed signal transmission without external magnetics.
• Provides robust galvanic isolation with 2500 Vrms rating and 25 kV/µs common-mode transient immunity.
• Features unidirectional 2/0 channel configuration optimized for general-purpose digital isolation.
• Automotive-grade reliability certified under AEC-Q100 standards for extended industrial temperature operation.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable signal isolation between microcontrollers and peripherals
• Medical equipment requiring safe patient isolation barriers

Procurement Notes

Verify the specific suffix '35' against official Analog Devices documentation to confirm pinout or electrical variations. Confirm package dimensions match the 8-SOIC specification. Ensure the component meets required automotive qualification standards if used in regulated environments. Cross-reference datasheet revisions to ensure compatibility with existing designs.

Selection Notes

Select this component when high-speed 25 Mbps isolation is required alongside automotive reliability. The 2/0 directionality suits applications where signals flow primarily one way. Consider the 4.3 mA power consumption per channel for thermal management. Verify that the 2500 Vrms isolation level meets system safety requirements.

Part Context

This part belongs to the ADuM1200 series of dual-channel digital isolators from Analog Devices. The series leverages silicon dioxide insulation and iCoupler technology to replace traditional optocouplers. The WSRZ35 variant indicates specific packaging and automotive qualification attributes within the broader product family.

Replacement Considerations

Official substitutes include ADUM1200CRZ-RL7 and ADUM1200ARZ-RL7. Verify functional equivalence regarding data rate and isolation voltage before substitution. Check for any differences in package tolerance or automotive grade certification.
