ADUM3100ARZ

Overview

The ADUM3100ARZ is a single-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides an isolation voltage of 2500 Vrms with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a typical propagation delay of 10.5 ns, rise/fall times of 3 ns, and a maximum power dissipation of 240 mW. It functions in unidirectional mode and is rated for operating temperatures between -40°C and +105°C.

Feature Summary

• Implements isolation using proprietary iCoupler magnetic coupling technology
• Provides high common-mode transient immunity for signal integrity
• Supports high-speed data transmission at 25 Mb/s
• Operates with low quiescent current consumption

Applications

• General-purpose digital isolation in industrial systems
• Isolation for microcontroller interfaces
• Signal isolation in measurement and control circuits

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging configuration. The base part number indicates tube packaging, while reel variants exist. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a single-channel, unidirectional isolator is required for applications needing moderate speed and robust transient immunity. Compare power consumption and package dimensions against alternative isolators if space or energy efficiency is critical. Verify that the 2500 Vrms isolation rating meets the safety requirements of the target application environment.

Part Context

This component belongs to the ADUM3100 series of digital isolators. It shares the same core functionality as the tape-and-reel variant ADUM3100ARZ-RL7 but differs in shipping packaging. The series leverages silicon dioxide insulation layers integrated into CMOS processes to achieve reliable signal transfer across isolation barriers without optical components.

Replacement Considerations

The ADUM3100ARZ-RL7 serves as a direct functional substitute with identical electrical characteristics, differing only in bulk packaging format.
