ADUM1200WURZ33-RL7

Overview

The ADUM1200WURZ33-RL7 is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It features unidirectional signal transmission with a data rate of 25Mbps and a common mode transient immunity (CMTI) of 25kV/µs. The device operates on a supply voltage range of 3V to 5.5V and supports an automotive grade qualification. It provides 2500Vrms isolation voltage within an 8-SOIC package, offering propagation delays of 45ns maximum and typical rise/fall times of 2.5ns.

Feature Summary

• Implements iCoupler magnetic coupling technology for high-speed digital isolation without external magnetics
• Provides robust common mode transient immunity suitable for noisy industrial environments
• Supports unidirectional data flow across two independent channels
• Qualified for automotive applications with extended temperature range capabilities

Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing reinforced isolation barriers
• Power monitoring systems with high voltage differential sensing

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout or packaging variations. Confirm current availability status as distribution channels may list obsolete or limited stock items. Ensure the selected variant matches the required automotive grade specifications for your application environment.

Selection Notes

Select this component when unidirectional isolation at 25Mbps is required with automotive reliability. Compare against standard commercial grades if operating conditions remain within lower temperature limits. Consider the 8-SOIC footprint constraints and verify that the 2500Vrms isolation rating meets system safety standards.

Part Context

This part belongs to the ADUM1200 series of dual-channel digital isolators from Analog Devices. The series leverages silicon dioxide insulation technology to replace traditional optocouplers. The WURZ33 suffix indicates specific packaging or tape-and-reel configuration details defined by the manufacturer for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers include ADUM1200WURZ and ADUM1200CRZ-RL7. Verify electrical parameter equivalence before substitution.
