ADUM6404CRIZ-RL

Overview

The ADUM6404CRIZ-RL is a four-channel digital isolator from Analog Devices, housed in a 16-pin SOIC package. It operates with a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides an insulation rating of 5000 Vrms and features a common-mode transient immunity of 25 kV/µs. Propagation delay is typically 60 ns, with operation supported across a temperature range of -40°C to +105°C. This component integrates an isoPower DC/DC converter for isolated power delivery.

Feature Summary

• Integrates an isoPower DC/DC converter to provide isolated power supply capability within the isolation barrier.
• Utilizes magnetic coupling technology to achieve galvanic isolation between input and output channels.
• Offers high common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing certified galvanic isolation barriers
• Power electronics interfaces for monitoring and control

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing components. Confirm that the CRIZ variant meets the required creepage distance specifications for your application safety standards. Ensure compatibility with the 16-SOIC footprint during PCB layout verification. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when four isolated channels are required alongside integrated isolated power generation. Compare against non-integrated isolators if external power management is preferred. Consider the 25 kV/µs CMTI rating for applications with high dv/dt noise. Verify that the 25 Mb/s data rate suffices for the target communication protocol speed.

Part Context

This part belongs to the ADUM6404 series of general-purpose digital isolators. It shares the same core isolation architecture and pinout configuration with the tube-packaged ADUM6404CRIZ variant. The primary distinction lies in the shipping format, with the -RL suffix denoting tape-and-reel packaging suitable for automated assembly processes.

Replacement Considerations

The ADUM6404CRIZ serves as a direct functional equivalent with identical electrical characteristics, differing only in packaging format (tube versus reel). No other cross-model substitutes share the exact combination of integrated isoPower and four-channel isolation in this specific package.
