ADUM6400CRWZ-RL

Overview

The ADUM6400CRWZ-RL is a four-channel digital isolator from Analog Devices, featuring integrated isolated DC/DC converters. It utilizes iCoupler magnetic coupling technology to provide high-speed data transmission with a maximum data rate of 25 Mb/s and a propagation delay of 60 ns. The device offers an isolation voltage of 5000 Vrms and a common-mode transient immunity of 25 kV/µs. Operating on a supply voltage range of 3 V to 5.5 V, it supports unidirectional signal paths across all channels. Packaged in a 16-SOIC (0.295 inch width) surface-mount format, the component operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates isolated DC/DC converters for each channel, eliminating the need for external power supplies on the secondary side.
• Employs iCoupler magnetic coupling technology to achieve robust galvanic isolation without optical components.
• Provides high common-mode transient immunity to ensure reliable operation in electrically noisy environments.

Applications

• Industrial automation systems requiring isolated communication interfaces.
• Medical equipment needing high-voltage isolation for patient safety.
• Power electronics control circuits involving motor drives or inverters.

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm that the part number matches the exact insulation voltage rating of 5000 Vrms required for your application safety standards. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check regional availability as distribution status may vary by location.

Selection Notes

Select this component when both high-speed data isolation and integrated secondary-side power are required. Compare against non-isolated power variants if only data isolation is needed. Consider the thermal dissipation capabilities given the internal power conversion. Verify that the 25 Mb/s data rate meets the system timing requirements.

Part Context

This part belongs to the ADUM6400 series, which focuses on quad-channel digital isolation with integrated power. It differs from the ADUM5404 series primarily in its higher insulation voltage rating of 5000 Vrms compared to lower-rated alternatives. The series represents Analog Devices' solution for compact, high-reliability isolation in space-constrained designs.

Replacement Considerations

Public confirmed substitute part numbers include ADUM6400CRWZ.
