ADUM1201WURZ35

Overview

The ADUM1201WURZ35 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 1 Mbps. The device provides 2500 Vrms isolation voltage and features a common-mode transient immunity of 25 kV/µs. Packaged in an 8-SOIC format, it functions bidirectionally with channel-to-channel matching and low pulse-width distortion.

Feature Summary

• Integrates high-speed CMOS and monolithic transformer technology for superior performance compared to optocouplers
• Supports bidirectional communication with 3 V/5 V level translation capabilities
• Provides precise timing characteristics including narrow pulse-width distortion and channel matching

Applications

• Lithium-ion battery stack monitors requiring signal and power isolation
• Industrial automation systems needing robust galvanic isolation
• Automotive electronics interfaces demanding high reliability

Procurement Notes

Verify the specific suffix WURZ35 against official manufacturer documentation, as this designation may indicate obsolete status or specialized packaging. Confirm current availability through authorized distributors, as standard variants like ADUM1201BRZ are more commonly stocked. Ensure compatibility with existing board layouts before procurement.

Selection Notes

Select this component when bidirectional data transfer is required across isolated boundaries. It is suitable for applications needing low power consumption at moderate data rates. Consider the 8-SOIC package constraints and verify thermal management requirements for operation up to 125°C. Compare against newer series if higher data rates are needed.

Part Context

This part belongs to the ADUM120x family of dual-channel digital isolators. These devices are designed to replace traditional optocouplers by offering smaller size, lower power, and better performance. The family includes various speed grades and package options to suit different interface requirements.

Replacement Considerations

Public records identify ADUM121N1WBRZ as a confirmed substitute for the discontinued ADUM1201WTRZ35 variant. Verify pinout and electrical specifications match before substitution.
