ADUM6404CRWZ

Overview

The ADUM6404CRWZ is a four-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It integrates an isolated DC/DC converter to provide 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 a temperature range of -40°C to +105°C. Packaged in a 16-lead SOIC.

Feature Summary

• Integrates an isolated DC/DC converter for on-chip power generation
• Provides high common-mode transient immunity via magnetic coupling
• Supports unidirectional signal transmission across four channels

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices as availability may vary by region.

Selection Notes

Select this component when integrated isolated power is required to simplify board design. Ensure the 400 mW power budget meets the load requirements of the isolated side. Verify that the 5000 Vrms isolation rating satisfies safety standards for the application environment.

Part Context

This part belongs to the ADuM640x series of IsoPwr digital isolators. It shares the SOIC-16 footprint with variants like the ADUM6400 but differs in channel directionality and internal power regulation capabilities compared to other family members.
