ADUM6400CRWZ

Overview

The ADUM6400CRWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It integrates an isolated DC/DC converter to provide power across the isolation barrier. The device operates on a single supply voltage ranging from 3 V to 5.5 V and supports data rates up to 25 Mb/s. Key electrical specifications include a 5000 Vrms isolation voltage, a common-mode transient immunity of 25 kV/µs, and a maximum propagation delay of 60 ns. It features unidirectional channels with a 1/0 input-to-output configuration. The component is housed in a 16-lead SOIC package and is rated for operation between -40°C and +105°C.

Feature Summary

• Integrates an isolated DC/DC converter to eliminate external power supplies on the isolated side
• Employs iCoupler magnetic coupling technology for high-speed signal transmission
• Provides robust common-mode transient immunity for noisy environments
• Offers four independent unidirectional signal channels in a compact surface-mount package

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power metering and energy management interfaces
• Automotive electronics with high-voltage isolation requirements

Procurement Notes

Verify the specific suffix (e.g., CRWZ) against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for any recent product change notices that may affect material composition or manufacturing location. Ensure the intended application voltage range aligns with the specified 3 V to 5.5 V operational limits.

Selection Notes

Select this component when integrated isolated power is required alongside high-speed digital isolation. The internal DC/DC converter simplifies board layout by removing external transformer components. Consider the 25 kV/µs CMTI rating for applications with significant noise. Verify that the 16-SOIC package dimensions fit the available PCB space. Compare performance metrics against non-isolated alternatives if cost reduction is critical and isolation is not mandatory.

Part Context

This part belongs to the ADUM6400 series, which focuses on providing integrated isolated power solutions. Unlike standard isolators, it combines signal isolation with power delivery in a single chip. This integration reduces system complexity and component count compared to discrete solutions using separate isolators and isolated power converters.

Replacement Considerations

ADUM6400CR is listed as a potential alternative variant within the same family.
