ADUM3472WCRSZ-RL7

Overview

The ADUM3472WCRSZ-RL7 is a four-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. 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 features bidirectional channel polarity and provides an insulation voltage rating of 2500 Vrms. It is housed in an SSOP-20 package and is qualified under the AEC-Q100 standard for automotive applications. The component functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent isolation channels with internal transformer drivers for efficient signal transfer.
• Features bidirectional data flow capability suitable for complex interface requirements.
• Includes integrated DC/DC converter functionality to provide isolated power supply capabilities.

Applications

• Automotive electronic systems requiring certified isolation components
• Industrial communication interfaces needing high-speed data transfer
• Medical equipment demanding strict electrical safety standards

Procurement Notes

Verify the specific suffix WCRSZ indicates automotive qualification and reel packaging configuration. Confirm that the bidirectional polarity matches system design requirements compared to unidirectional variants. Ensure compatibility with the SSOP-20 footprint during PCB layout. Check current availability status as distribution may be limited or subject to allocation constraints.

Selection Notes

Select this variant when automotive reliability certification is mandatory for the application. Choose over non-automotive versions if operating conditions exceed standard industrial limits. Consider the bidirectional nature for protocols requiring return data paths. Verify that the 2500 Vrms isolation level meets the specific safety clearance requirements of the target system design.

Part Context

This component belongs to the ADUM3472 series of digital isolators manufactured by Analog Devices. It shares the core magnetic coupling architecture with other members of the family but differs in qualification grade and packaging format. The series is designed to replace traditional optocouplers in modern high-speed digital isolation applications.

Replacement Considerations

Direct substitutes include other ADUM3472 series parts with matching automotive qualification and bidirectional specifications. Verify pinout compatibility before replacing with similar offerings from different manufacturers.
