ADUM1100ARZ-RL7

Overview

The ADUM1100ARZ-RL7 is a single-channel digital isolator from Analog Devices, utilizing iCoupler technology with monolithic air core transformers. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. Key electrical parameters include an isolation voltage of 2500 Vrms, a typical propagation delay of 18 ns, and rise/fall times of 3 ns. The device draws 800 uA of operating current and dissipates 240 mW of power. It functions in unidirectional mode with a pulse width tolerance of 40 ns across an industrial temperature range of -40 C to +125 C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air core transformer technology for magnetic coupling isolation.
• Provides robust galvanic isolation capability suitable for general-purpose digital signal transmission.
• Supports unidirectional data flow with low power consumption characteristics.

Applications

• General-purpose digital signal isolation
• Industrial communication interfaces
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation as availability varies by region. Check manufacturer lifecycle status for potential obsolescence or limited supply constraints before finalizing procurement plans.

Selection Notes

Select this component for applications requiring single-channel unidirectional isolation with moderate speed requirements. Ensure the SOIC-8 package fits the design constraints. Verify that the 2500 Vrms isolation rating meets system safety standards. Consider the 3 V to 5.5 V supply range compatibility with existing logic levels.

Part Context

This part belongs to the ADUM1100 series of digital isolators manufactured by Analog Devices Inc. It is distinct from other variants like the tube-packaged ADUM1100ARZ by its reel packaging format. The series leverages iCoupler technology to replace traditional optocouplers in many designs.

Replacement Considerations

The ADUM1100ARZ serves as a non-reel equivalent variant within the same family. Verify pinout and electrical specifications match exactly before substitution. No other direct cross-model substitutes are confirmed in public documentation.
