ADUM6401ARIZ

Overview

The ADUM6401ARIZ is a four-channel digital isolator from Analog Devices, featuring integrated isolated DC/DC converters. It operates within a 3 V to 5.5 V supply range and supports data rates up to 25 Mb/s. The device provides 5000 Vrms isolation voltage with magnetic coupling technology. Key electrical parameters include a propagation delay of 55 ns, rise/fall times of 2.5 ns typical, and a common mode transient immunity of 25 kV/µs. It functions in temperatures from -40°C to +105°C and is housed in a 16-lead SOIC package.

Feature Summary

• Integrates isolated power supplies to eliminate external transformer requirements
• Utilizes iCoupler magnetic coupling technology for signal transmission
• Provides high common mode transient immunity for noisy environments
• Supports unidirectional data flow across four independent channels

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power metering applications with high voltage separation
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix 'IZ' against official Analog Devices documentation to confirm creepage distance and safety certification ratings. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the ordering part number matches the required tape and reel or tube packaging format specified in the manufacturer's current datasheet revision.

Selection Notes

Select this component when both signal isolation and isolated power delivery are required in a single package. Compare the 55 ns propagation delay against system timing constraints. Evaluate the 5000 Vrms isolation rating against regulatory safety standards for the target application. Consider the 16-SOIC footprint for PCB layout compatibility compared to other channel counts.

Part Context

This part belongs to the ADuM640x family of IsoPower digital isolators. It shares architectural similarities with the ADUM6400 and ADUM6402 series but differs in specific parameter tolerances and packaging options. The family is designed to simplify designs by combining isolation barriers with power conversion capabilities.

Replacement Considerations

Official substitutes include ADUM6401ARWZ and ADUM6401ARWZ-RL. Verify pinout compatibility and isolation voltage ratings before substitution. Cross-reference safety certifications such as UL and VDE if applicable to the design.
