ADUM5403ARWZ-RL

Overview

The ADUM5403ARWZ-RL is a quad-channel digital isolator featuring an integrated isolated DC-to-DC converter. It utilizes iCoupler technology for magnetic coupling, providing four independent isolation channels with unidirectional signal transmission. The device supports data rates up to 1 Mbps and offers a basic isolation voltage of 2500 Vrms. It operates within a supply voltage range of 3 V to 5.5 V and delivers up to 500 mW of regulated isolated power. The component is housed in a 16-SOIC package and functions across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates a high-performance isolated DC-to-DC converter capable of delivering up to 500 mW of regulated power, eliminating the need for external isolated power supplies.
• Employs iCoupler chip-scale transformer technology to provide robust magnetic isolation for both logic signals and power feedback paths.
• Features four independent unidirectional isolation channels designed for general-purpose digital signal transmission.

Applications

• Industrial automation systems requiring galvanic isolation between control and sensor interfaces
• Medical equipment needing certified isolation for patient-connected circuits
• Power metering applications utilizing ISOPWR technology for simplified board design

Procurement Notes

Verify the specific suffix (RL) indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required channel configuration and isolation voltage ratings for the target application environment.

Selection Notes

Select this component when a single-chip solution for both signal isolation and isolated power generation is required. It is suitable for designs needing four unidirectional channels with high common-mode transient immunity. Consider the 16-SOIC footprint and thermal dissipation capabilities during PCB layout planning.

Part Context

This part belongs to the ADUM540x series of IsoPower digital isolators from Analog Devices. It shares the same core architecture as the ADUM5403ARWZ but differs in packaging format. The series is characterized by its ability to combine high-speed digital isolation with efficient power conversion in a compact form factor.

Replacement Considerations

The ADUM5403ARWZ is a pin-compatible alternative available in tube packaging. Verify that the packaging difference does not impact automated assembly processes before substitution.
