ADUM1201WURZ53-RL7

Overview

The ADUM1201WURZ53-RL7 is a dual-channel digital isolator from Analog Devices Inc., utilizing iCoupler technology for signal transmission across isolation barriers. It features two unidirectional channels with a data rate of 25 Mbps and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a wide operating temperature range of -40°C to +125°C. Packaged in an 8-SOIC (0.154 inch, 3.90 mm wide) surface-mount package, it offers high common-mode transient immunity of 25 kV/µs. This component is designated as obsolete and no longer manufactured.

Feature Summary

• Implements magnetic coupling via iCoupler technology for robust digital isolation without optical components.
• Provides bidirectional communication capabilities with 3 V/5 V level translation support.
• Delivers precise timing characteristics including low pulse-width distortion and channel-to-channel matching.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing certified safety isolation
• Automotive electronics interfaces

Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Analog Devices Inc. Procurement should focus on verified parameter-equivalent replacements such as the ADUM1201WURZ or ADUM1201WURZ-RL7. Buyers must confirm current availability status through authorized distributors, as stock may be limited or restricted. Verify that replacement parts meet the same AEC-Q100 qualification and SOIC-8 package dimensions to ensure mechanical and electrical compatibility.

Selection Notes

Select this component for applications demanding high-speed data transfer up to 25 Mbps with reliable isolation. The wide temperature range and high CMTI make it suitable for harsh environments. Consider the obsolete status when planning long-term production; alternative variants like the ADUM120N series offer higher data rates if needed. Ensure the design accommodates the 8-SOIC footprint and validates power consumption at the target operating frequency.

Part Context

The ADUM1201 belongs to the ADuM120x family of dual-channel digital isolators. These devices combine high-speed CMOS and monolithic transformer technology to provide performance superior to traditional optocouplers. The family is designed for general-purpose isolation with UL, CSA, and VDE safety approvals. The WURZ suffix indicates a wider SOIC package variant optimized for specific thermal and spacing requirements.

Replacement Considerations

Public confirmed substitutes include ADUM1201WURZ and ADUM1201WURZ-RL7. These are parameter-equivalent alternatives available from Analog Devices Inc. Verify that the substitute matches the 8-SOIC package and 2500 Vrms isolation rating.
