ADUM6403CRIZ

Overview

The ADUM6403CRIZ is a four-channel digital isolator from Analog Devices, utilizing isoPower technology to integrate an isolated DC-to-DC converter with data isolation in a single SOIC-16 package. It supports unidirectional signal transmission at data rates up to 25 Mb/s with a propagation delay of 60 ns. The device offers high insulation voltage of 5000 Vrms and maintains an 8 mm creepage distance for enhanced safety. Operating on a supply voltage range of 3 V to 5.5 V, it functions reliably within a temperature range of -40°C to +105°C.

Procurement Notes

Verify the specific suffix (CRIZ) against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Ensure the SOIC-16 package matches your PCB footprint requirements. Confirm that the integrated DC/DC converter meets your power budget needs before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring simultaneous power delivery and data isolation across a barrier. The integrated isoPower technology eliminates the need for external isolated power supplies, simplifying board layout. Consider the 25 Mb/s data rate limit and 60 ns propagation delay for timing-sensitive applications.

Part Context

This part belongs to the ADuM640x family of quad-channel digital isolators. These devices are designed to replace traditional optocouplers and transformer-based solutions in space-constrained designs. The series emphasizes reliability and performance in harsh electromagnetic environments common in industrial settings.

Replacement Considerations

Check Analog Devices datasheets for direct pin-compatible alternatives within the ADuM640x series. Verify if other variants offer different channel counts or isolation voltages suitable for your specific design constraints.
