ADUM6400ARWZ

Overview

The ADUM6400ARWZ is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides 5000 Vrms insulation rating using magnetic coupling technology. The device supports data rates up to 25 Mb/s with a typical propagation delay of 55 ns. It operates on a supply voltage range of 3 V to 5.5 V and consumes 12 mA of operating power. The component is housed in a 16-pin SOIC package and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across isolation barriers
• Provides four independent unidirectional signal channels for high-density digital isolation
• Utilizes iCoupler magnetic coupling technology for robust signal transmission

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Data acquisition modules with high common-mode transient immunity

Procurement Notes

Verify the specific suffix (RWZ) confirms the SOIC-16 package and tape/reel or tube availability as per current distributor listings. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 5kV isolation rating meets your system's safety standards before finalizing procurement.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a single package. It is suitable for designs needing 4-channel isolation with high CMTI. Consider the 12 mA quiescent current impact on overall system efficiency compared to discrete solutions.

Part Context

This part belongs to the ADUM6400 series, which combines digital isolation with integrated power conversion. It serves as a compact alternative to separate isolator and DC/DC converter components, reducing board space and design complexity in industrial and medical applications.

Replacement Considerations

Check ADUM6401 variants for bidirectional channel configurations. Verify ADUM5404 series for lower isolation ratings if 2500 Vrms suffices. Ensure pin compatibility and thermal performance match existing PCB layouts.
