ADUM6403ARIZ-RL

Overview

The ADUM6403ARIZ-RL is a four-channel digital isolator manufactured by Analog Devices Inc., housed in a 16-pin SOIC package. It features magnetic coupling technology with an insulation voltage of 5000 Vrms and supports data rates up to 25 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and includes an integrated DC/DC converter. It exhibits a propagation delay of 60 ns and maintains a common mode transient immunity of 25 kV/µs. The component functions unidirectionally across an industrial temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent signal channels with a built-in isolated power supply for simplified design
• Utilizes on-chip transformer technology to provide high isolation performance without external components
• Offers robust noise immunity against fast-rising voltage transients at the isolation boundary

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages
• Medical equipment needing certified safety isolation for patient-connected circuits
• Power electronics interfaces such as motor drives and solar inverters

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the manufacturer part number matches exactly, as Analog Devices uses distinct codes for tape-and-reel versus tube quantities. Check current availability status as distribution may vary. Ensure compliance with RoHS directives if required for your assembly process. Validate that the SOIC-16 footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Choose this component when four isolated channels are necessary alongside an integrated power source. It suits designs demanding high common-mode transient immunity and moderate data speeds. Consider the thermal characteristics of the SOIC-16 package for your enclosure. Evaluate the 5000 Vrms isolation rating against your system's safety requirements. Compare power consumption metrics if battery operation is a constraint.

Part Context

This part belongs to the ADUM6403 series of digital isolators from Analog Devices. The series focuses on providing reliable signal transmission across isolation barriers using capacitive or magnetic coupling technologies. The ADUM6403 variant specifically integrates the power conversion stage, distinguishing it from passive isolator families. It serves as a key interface solution in modern electronic systems where electrical safety and noise reduction are critical.
