ADUM5403WCRWZ-1

Overview

The ADUM5403WCRWZ-1 is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower DC/DC converter. It provides four unidirectional signal channels with data rates up to 25 Mb/s and a common-mode transient immunity of 50 kV/µs. The device operates on a single 3 V to 5.5 V supply and includes a regulated 3.3 V or 5.0 V output from the isolated side. It utilizes magnetic coupling technology for isolation, offering a 2500 Vrms insulation voltage. Packaged in a 16-pin SOIC with a 7.50 mm wide body, it supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates a high-efficiency DC/DC converter to provide isolated power alongside signal transmission
• Employs proprietary iCoupler magnetic coupling technology for robust signal isolation
• Features a wide-body 16-lead SOIC package designed to meet stringent creepage distance requirements

Applications

• Industrial automation systems requiring galvanic isolation between control and field devices
• Medical equipment needing reinforced isolation for patient safety compliance
• Automotive electronics utilizing CAN bus or LIN bus communication interfaces
• Power metering applications involving high-voltage sensing circuits

Procurement Notes

Verify the specific suffix designation to confirm the package width and reel configuration. Ensure that the required output voltage of the integrated converter matches the application needs. Confirm AEC-Q100 qualification status if automotive reliability standards are mandatory. Check moisture sensitivity levels and reflow soldering profiles during assembly planning.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a compact footprint. Compare channel count and data rate requirements against other members of the ADUM540x family. Evaluate thermal performance under maximum load conditions due to the integrated converter. Consider the wide-body package benefits for high-voltage isolation standards compared to standard narrow packages.

Part Context

This part belongs to the ADUM540x series of quad-channel digital isolators. It shares architectural similarities with the ADUM5401 and ADUM5402 but offers distinct channel configurations and power options. The series represents Analog Devices' solution for combining high-speed data isolation with efficient power conversion in industrial and automotive environments.

Replacement Considerations

The ADUM5401WCRWZ-1 serves as a verified substitute within the same product family.
