ADUM6400ARIZ-RL

Overview

The ADUM6400ARIZ-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isolated DC/DC converter. It provides four unidirectional signal channels with a data rate of 25 Mb/s and a propagation delay of 60 ns. The device offers 5000 Vrms insulation voltage and operates within a supply voltage range of 3 V to 5.5 V. It is housed in a 16-lead SOIC package with increased creepage distance and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates an isolated DC/DC converter to simplify system design by eliminating external power components.
• Provides four unidirectional signal channels for high-speed digital isolation.
• Utilizes iCoupler magnetic coupling technology for robust signal transmission.

Applications

• Industrial automation systems requiring multi-channel isolation
• Medical equipment with strict safety isolation requirements
• Power metering applications needing galvanic separation

Procurement Notes

Verify the specific suffix 'ARIZ' against the official datasheet to confirm the package type and temperature rating. Confirm availability status as distribution may vary. Ensure the reel packaging matches the production line requirements. Check for any recent process change notices that might affect compatibility.

Selection Notes

Select this component when a single IC solution is needed for both signal isolation and isolated power generation. It is suitable for designs requiring four independent signal paths with high common-mode transient immunity. Consider the 16-lead SOIC footprint during PCB layout planning.

Part Context

This part belongs to the ADUM6400 series of quad-channel isolators with integrated power converters. It is designed to replace bulky discrete isolation solutions. The ARIZ variant specifically denotes the SOIC-16 package with extended creepage distance for enhanced safety compliance.

Replacement Considerations

Check for ADUM6400CRIZ-RL if a different temperature grade or package option is required. Verify pinout compatibility before substitution. Consult the manufacturer's guide for approved replacements to ensure electrical parameter matching.
