ADUM1201WURZ

Overview

The ADUM1201WURZ is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides bidirectional communication with a data rate up to 25 Mbps and isolation voltage of 2500 Vrms. The device operates on a supply voltage range of 2.7 V to 5.5 V, featuring low power consumption of 4.3 mA per channel at 25 Mbps. Key electrical parameters include a maximum propagation delay of 50 ns, typical rise/fall times of 2.5 ns, and a common-mode transient immunity of 25 kV/µs. It is housed in an 8-SOIC package.

Feature Summary

• Bidirectional communication capability with integrated level translation between 3 V and 5 V domains
• High-speed data transmission supporting rates from DC to 25 Mbps using NRZ signaling
• Robust noise immunity characterized by high common-mode transient rejection capabilities

Applications

• Industrial automation systems requiring galvanic isolation for sensor interfaces
• Medical equipment needing compliant signal isolation between circuits
• Automotive electronics utilizing AEC-Q100 qualified components
• Power management systems isolating control signals from high-voltage sections

Procurement Notes

Verify the specific suffix 'WURZ' against current manufacturer documentation to confirm package dimensions and moisture sensitivity classification. Ensure compliance with RoHS directives and check for any recent product change notices affecting wafer fabrication sites or assembly locations prior to final procurement authorization.

Selection Notes

Select this component when bidirectional data transfer across an isolation barrier is required within a single 8-lead package. It is suitable for applications demanding precise timing characteristics and low pulse-width distortion. Consider alternative variants if unidirectional flow or different speed grades better match the system requirements.

Part Context

This part belongs to the ADuM120x family of dual-channel digital isolators developed by Analog Devices Inc. The series leverages monolithic transformer technology to replace traditional optocouplers, offering superior reliability and performance. The ADUM1201 variant specifically supports bidirectional channels, distinguishing it from unidirectional models like the ADUM1200.
