ADUM6402CRIZ-RL

Overview

The ADUM6402CRIZ-RL is a quad-channel digital isolator from Analog Devices, housed in a 16-SOIC surface-mount package. It provides four independent signal channels with unidirectional data flow at a maximum data rate of 25 Mb/s. The device features magnetic coupling isolation technology with an insulation voltage rating of 5000 Vrms and an 8mm creepage distance. It operates on a single power supply ranging from 3 V to 5.5 V and includes an integrated DC/DC converter for isolated power delivery. Typical propagation delay is 60 ns, with rise and fall times of 2.5 ns. The component functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent digital signal channels with unidirectional transmission capability
• Incorporates an internal isolated DC/DC converter for self-powered operation
• Utilizes capacitive or magnetic coupling technology for high-voltage isolation
• Provides robust electrical isolation with 5000 Vrms insulation rating

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics interfaces such as motor drives and inverters
• Instrumentation and measurement devices

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Check RoHS compliance status via official documentation. Ensure the SOIC-16 package matches your PCB footprint requirements. Validate that the 5000 Vrms isolation rating meets your system's safety standards.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required in a compact form factor. The integrated DC/DC converter simplifies design by eliminating external isolated power supplies. Consider the 25 Mb/s data rate limit for high-speed communication needs. Verify thermal performance within the specified -40°C to +105°C range for your application environment.

Part Context

This part belongs to the ADUM6402 series of quad-channel digital isolators. It shares the same core functionality and pinout with the non-reel version ADUM6402CRIZ, differing primarily in packaging format. The series is designed for applications requiring multiple isolated signals in a single package, reducing board space compared to discrete solutions.

Replacement Considerations

The ADUM6402CRIZ is a direct alternative differing only in packaging (tube vs. reel). Cross-reference with other ADUM64xx series parts if channel count or data rate requirements differ. Verify pin compatibility before substituting with similar isolators from other manufacturers.
