ADUM6403CRWZ

Overview

The ADUM6403CRWZ is a four-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It integrates an isolated DC/DC converter capable of delivering up to 400 mW of regulated power at 5.0 V or 3.3 V. The device features a 5000 Vrms isolation voltage and supports data rates up to 25 Mb/s with a maximum propagation delay of 60 ns. It operates within a supply voltage range of 3 V to 5.5 V and functions across temperatures from -40°C to +105°C. Housed in a 16-lead SOIC package, it offers high common-mode transient immunity.

Feature Summary

• Integrates an isolated DC/DC converter providing up to 400 mW of regulated power
• Utilizes iCoupler magnetic coupling technology for signal transmission
• Provides 5000 Vrms basic isolation rating between channels

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation
• Power metering and energy management circuits

Procurement Notes

Verify the specific suffix (e.g., CRWZ) against the official datasheet to ensure correct temperature grade and packaging configuration. Confirm that the integrated DC/DC converter requirements align with the target application's power budget. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when a single solution is needed for both signal isolation and isolated power generation. Ensure the load does not exceed the 400 mW output capability of the internal converter. Consider the 16-pin SOIC footprint during PCB layout design.

Part Context

This part belongs to the ADuM640x family of IsoPower digital isolators. It combines four independent logic channels with a high-efficiency isolated power supply, reducing component count compared to discrete solutions using separate isolators and converters.
