ADUM6400ARWZ-RL

Overview

The ADUM6400ARWZ-RL is a four-channel digital isolator from Analog Devices, featuring integrated IsoPower DC/DC converters. It provides 5000 Vrms isolation voltage with magnetic coupling technology. The device supports data rates up to 25 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. Key electrical parameters include a propagation delay of 60 ns, rise/fall times of 2.5 ns, and a pulse width distortion of 1000 ns. It functions in unidirectional mode across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates isolated DC/DC power conversion alongside signal isolation channels
• Utilizes iCoupler magnetic coupling technology for high reliability
• Provides robust common-mode transient immunity for noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix 'ARWZ-RL' against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the datasheet. Confirm that the intended application meets the required isolation voltage standards and thermal dissipation limits for the SOIC-16 package.

Selection Notes

Select this component when both signal isolation and isolated power delivery are required in a single package. It is suitable for designs needing high channel density and reduced board space compared to discrete solutions. Consider the 5000 Vrms rating for applications demanding reinforced isolation between primary and secondary sides.

Part Context

This part belongs to the ADuM6400 series, which combines four-channel digital isolation with integrated power management. It is designed to simplify system design by reducing component count and improving reliability in industrial and medical applications where safety and noise immunity are critical.

Replacement Considerations

Check for direct substitutes within the ADUM6400 family or the ADUM5404 series if lower isolation voltage is acceptable. Verify pinout compatibility and electrical parameter overlaps before substitution.
