ADUM4472ARIZ-RL

Overview

The ADUM4472ARIZ-RL is a four-channel digital isolator from Analog Devices Inc., utilizing magnetic coupling technology within the IsoPower and iCoupler series. It provides 5000 Vrms isolation voltage with a common-mode transient immunity of 25 kV/µs. The device supports data rates up to 25 Mb/s, featuring maximum propagation delays of 60 ns for both rising and falling edges. It operates on supply voltages between 3 V and 5.5 V, housed in a 20-SOIC package.

Feature Summary

• Integrates four unidirectional channels with integrated isolated power capability
• Employs magnetic coupling technology for high-speed signal transmission
• Provides robust protection against common-mode transients

Applications

• PWM control and transformer driver circuits
• Industrial automation systems requiring galvanic isolation
• Power electronics interfaces

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm the 'I' designation corresponds to the industrial temperature range of -40°C to +105°C. Ensure compatibility with 3 V to 5.5 V supply rails. Check current availability status as distribution may vary. Validate RoHS compliance documentation upon receipt.

Selection Notes

Select this component for applications requiring four isolated channels with integrated power delivery. It is suitable where high common-mode noise rejection is critical. Compare against the ADUM4470 variant if lower speed requirements exist. Ensure the SOIC-20 footprint fits the design constraints. Verify input/output logic levels match the system requirements.

Part Context

This part belongs to the ADuM447x family of digital isolators. It shares architectural similarities with the ADUM4470 and ADUM4473 models but differs in channel count and speed specifications. The family utilizes proprietary iCoupler technology to replace traditional optocouplers in many designs.
