ADUM1201WURZ55

Overview

The ADUM1201WURZ55 is a dual-channel digital isolator utilizing iCoupler technology, which integrates high-speed CMOS and monolithic transformer capabilities. It provides galvanic isolation with a rated voltage of 2500Vrms for one minute per UL1577 standards. The device supports data rates up to 25Mbps and features a common-mode transient immunity (CMTI) of 25kV/µs. It operates within a supply voltage range of 3V to 5.5V and functions across an extended temperature range of -40°C to 125°C. Packaged in a narrow-body 8-SOIC format, it offers bidirectional communication and level translation between 3V and 5V domains.

Feature Summary

• Integrates high-speed CMOS and monolithic transformer technology for robust signal transmission
• Provides bidirectional communication with automatic 3V/5V level translation
• Delivers high common-mode transient immunity exceeding 25kV/µs
• Ensures precise timing characteristics with minimal pulse-width distortion

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing reinforced galvanic isolation
• Automotive electronics adhering to AEC-Q100 reliability standards
• General-purpose digital isolation in noisy environments

Procurement Notes

Verify the specific suffix '55' against official Analog Devices documentation to confirm package variant or tape-and-reel specifications, as standard listings often reference 'WURZ'. Confirm current availability status, as some variants may be subject to limited supply or end-of-life notices. Ensure compliance with RoHS3 requirements and check for any recent Product Change Notices affecting manufacturing sites or materials.

Selection Notes

Select this component when bidirectional data transfer and level shifting are required within a single isolator package. It is suitable for applications demanding high CMTI to withstand rapid voltage transients. Consider the 8-SOIC footprint for space-constrained designs. Verify that the 25Mbps data rate meets system throughput needs and that the operating temperature range aligns with environmental conditions.

Part Context

This part belongs to the ADuM120x series of dual-channel digital isolators from Analog Devices. The series leverages iCoupler technology to replace traditional optocouplers, offering superior performance in speed, power consumption, and size. The WURZ55 designation indicates a specific packaging or reel configuration within the broader ADUM1201 product family.

Replacement Considerations

ADUM1201WURZ is a parameter-equivalent alternative within the same series. Other compatible options include ADUM1201ARZ and ADUM1201WTRZ, depending on required packaging and reel specifications. Verify pinout compatibility and electrical parameters before substitution.
