ADUM1100URZ-RL7

Overview

The ADUM1100URZ-RL7 is a single-channel digital isolator utilizing iCoupler technology, which integrates high-speed CMOS logic and monolithic air-core transformer technology on a single silicon chip. It provides galvanic isolation with a maximum operating voltage of 5.5 V and a minimum of 3 V. The device supports data rates up to 100 Mb/s with a typical propagation delay of 18 ns. It operates within a temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air-core transformer technology for signal transmission
• Provides robust galvanic isolation between input and output circuits
• Supports unidirectional data transmission at speeds up to 100 Mb/s

Applications

• High-speed isolated communication interfaces
• Industrial automation control systems
• Medical equipment requiring electrical safety isolation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Ensure supply chain sources provide valid RoHS compliance documentation. Check for any recent product change notices regarding wire conversion or material updates from Analog Devices Inc.

Selection Notes

Select this component for applications requiring single-channel isolation with moderate speed requirements. It is suitable where low power consumption and small form factor are priorities. Consider the 2500 Vrms isolation rating against system safety standards. Evaluate the 100 Mb/s data rate capability against the specific bus speed needs of the target application.

Part Context

This part belongs to the ADuM1100 series of digital isolators from Analog Devices Inc. The series leverages iCoupler technology to replace traditional magnetic components. The URZ-RL7 designation specifies the unbuffered version in an SOIC-8 package supplied in a tape and reel format for automated assembly processes.

Replacement Considerations

Direct replacements include other single-channel iCoupler isolators from Analog Devices such as the ADuM1101 or ADuM1201, depending on channel count and speed requirements. Verify pin compatibility and isolation voltage ratings before substitution.
