ADUM6400ARIZ

Overview

The ADUM6400ARIZ is a four-channel digital isolator from Analog Devices, featuring integrated isolated DC/DC converters. It operates within a supply voltage range of 3 V to 5.5 V 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 60 ns, rise/fall times of 2.5 ns typical, and a common-mode transient immunity of 25 kV/µs. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates isolated power supplies directly within the digital isolator package
• Provides high-speed unidirectional signal transmission via magnetic coupling
• Ensures robust galvanic isolation with 5000 Vrms insulation rating
• Features wide common-mode transient immunity for noisy environments

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reinforced safety isolation
• Power electronics monitoring and control circuits
• Automotive sensor interface modules

Procurement Notes

Verify the specific suffix ARIZ indicates the SOIC-16 package with 8mm creepage distance. Confirm RoHS compliance status through official manufacturer documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the ordering part number matches the exact datasheet revision for pinout compatibility.

Selection Notes

Select this component when integrated isolated power is required alongside four-channel digital isolation. Compare against non-isolated power variants if external power solutions are preferred. Consider the 25 Mb/s data rate limit for high-speed applications. Evaluate the SOIC-16 footprint constraints against available PCB space.
