ADUM3473WCRSZ-RL7

Overview

The ADUM3473WCRSZ-RL7 is a quad-channel digital isolator from Analog Devices, housed in an SSOP-20 surface-mount package. It operates on a supply voltage range of 3 V to 5.5 V and supports bidirectional data transmission at speeds up to 25 Mb/s. The device provides 2500 Vrms isolation via magnetic coupling technology. It functions within a temperature range of -40°C to +105°C and holds AEC-Q100 qualification for automotive applications.

Feature Summary

• Integrates four independent bidirectional channels with internal transformer drivers for compact system design
• Provides robust galvanic isolation through magnetic coupling technology to protect sensitive circuitry
• Meets AEC-Q100 automotive qualification standards for reliability in demanding environments

Applications

• Automotive electronic control units requiring certified isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing high-reliability signal isolation

Procurement Notes

Verify the specific suffix WCRSZ against official datasheets to confirm automotive grade status and packaging type. Confirm availability status directly with authorized distributors as supply may be restricted. Ensure compatibility with existing PCB footprints for SSOP-20 packages during integration planning.

Selection Notes

Select this component when automotive certification is mandatory for digital isolation requirements. Compare propagation delay and power consumption against non-automotive variants if cost sensitivity exists. Verify that the bidirectional channel configuration matches the specific signal flow needs of the target application interface.

Part Context

This part belongs to the ADUM347x series of quad-channel digital isolators. It shares the same core isolation architecture and pinout structure as other members like the ADUM3473CRSZ but differs in qualification level and operating temperature specifications. The series is designed for high-density isolation applications.

Replacement Considerations

Direct substitutes include other ADUM3473 variants such as ADUM3473CRSZ or ADUM3473ARSZ, provided they meet the required environmental and qualification standards for the specific application context.
