ADUM6403CRIZ-RL

Overview

The ADUM6403CRIZ-RL is a four-channel digital isolator manufactured by Analog Devices Inc., housed in a 16-lead SOIC package with increased creepage distance. It operates on a single power supply ranging from 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides an isolation voltage of 5000 Vrms and features a typical propagation delay of 60 ns. It functions within a temperature range of -40°C to +105°C and utilizes magnetic coupling technology for signal transmission.

Feature Summary

• Integrates four independent unidirectional channels for simultaneous signal isolation
• Incorporates an integrated DC/DC converter to generate isolated power supplies
• Utilizes silicon dioxide (SiO2) insulation technology for high reliability
• Features enhanced creepage distances to meet stringent safety standards

Applications

• Industrial automation systems requiring galvanic separation
• Medical equipment needing reinforced isolation barriers
• Power metering circuits for accurate current sensing
• Motor control applications involving IGBT or MOSFET drive signals

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing components. Confirm that the CRIZ designation corresponds to the correct temperature grade and package variant required for your design. Ensure compatibility with existing PCB footprints, as the SOIC-16 package dimensions must match your layout specifications precisely before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are necessary within a single footprint. The integrated power supply simplifies design by eliminating external isolated converters. Consider the 25 Mb/s data rate limit for high-speed communication needs. Evaluate the thermal performance requirements against the specified operating temperature range to ensure stable operation under load conditions.

Part Context

This part belongs to the ADUM6403 series of digital isolators. It shares architectural similarities with other members of the family but differs in channel count and specific electrical characteristics. The series is designed to replace traditional optocouplers in modern electronic designs, offering superior performance metrics and smaller form factors for space-constrained applications.

Replacement Considerations

Direct substitutes include other ADUM640x variants with matching channel counts. Verify pinout compatibility before swapping with similar devices from different manufacturers. Ensure replacement parts maintain equivalent isolation voltage ratings and creepage distances to preserve system safety certifications.
