ADUM6403ARWZ

Overview

The ADUM6403ARWZ is a general-purpose digital isolator from Analog Devices Inc., housed in a 16-SOIC package. It integrates four unidirectional channels with an internal DC/DC converter, supporting data rates up to 25 Mb/s and offering 5000 Vrms insulation voltage. The device operates within a supply voltage range of 3 V to 5.5 V, features a propagation delay of 60 ns, and withstands a common-mode transient immunity of 25 kV/µs. Designed for robust isolation in industrial applications, it functions across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates four unidirectional signal channels with an on-chip DC/DC converter for complete isolation.
• Provides high-voltage isolation capability rated at 5000 Vrms between input and output sides.
• Delivers fast signal transmission with a maximum data rate of 25 Mb/s per channel.
• Ensures signal integrity under high electromagnetic interference with 25 kV/µs common-mode transient immunity.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics monitoring and gate drive circuits
• Data acquisition systems with isolated sensor interfaces

Procurement Notes

Verify the specific ordering suffix (e.g., ARWZ vs. ARWZ-RL) against official Analog Devices documentation to ensure correct packaging configuration. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when high-density four-channel isolation is required within a single SOIC-16 footprint. The integrated DC/DC converter simplifies design by eliminating external power supplies for the isolated side. Ensure the application demands unidirectional signal flow and can accommodate the specified 60 ns propagation delay. Verify that the 5000 Vrms isolation rating aligns with the system's safety standards and regulatory requirements.

Part Context

This device belongs to the ADUM series of capacitive and magnetic coupling digital isolators manufactured by Analog Devices. It represents a solution for replacing traditional optocouplers in modern designs, offering superior performance metrics such as higher speed and better reliability. The ADUM6403ARWZ specifically targets applications needing robust, high-voltage isolation with integrated power management capabilities.

Replacement Considerations

Consult Analog Devices official documentation for qualified alternative part numbers within the ADUM family. Verify pinout compatibility and electrical parameter equivalence before substituting. No direct public substitute part numbers are confirmed in the provided source material.
