ADUM1201WURZ35-RL7

Overview

The ADUM1201WURZ35-RL7 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 25 Mbps with a maximum propagation delay of 150 ns. The device provides 2500 Vrms isolation voltage and features a common-mode transient immunity of 25 kV/µs. Packaged in an 8-lead SOIC, it is AEC-Q100 qualified for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Implements iCoupler magnetic coupling technology for high-speed signal transmission without optical components.
• Provides bidirectional communication capabilities with integrated 3 V/5 V level translation.
• Ensures precise timing characteristics including minimal pulse-width distortion and channel-to-channel matching.

Applications

• Automotive electronic systems requiring certified isolation interfaces
• Industrial control networks needing robust noise immunity
• Medical equipment demanding strict safety compliance

Procurement Notes

Verify the specific suffix WURZ35 against official Analog Devices documentation to confirm manufacturing site and material composition changes. Confirm current availability status as distribution channels may list obsolete or limited stock items. Ensure compatibility with existing PCB footprints and reflow profiles before procurement.

Selection Notes

Select this component when bidirectional data transfer is required alongside high common-mode transient immunity. It serves as a direct replacement for optocouplers in space-constrained designs due to its narrow body package. Consider the AEC-Q100 qualification if deploying in automotive environments where thermal stability is critical.

Part Context

This part belongs to the ADuM120x series of dual-channel digital isolators. It shares the core iCoupler architecture with variants like ADUM1200 but differs in channel configuration and directionality. The series is designed to replace traditional optocouplers while offering superior performance metrics and smaller form factors.
