ADUM6401CRWZ-RL

Overview

The ADUM6401CRWZ-RL is a quad-channel digital isolator from Analog Devices Inc., featuring the isoPower technology with an integrated isolated DC-to-DC converter. It provides 5000Vrms isolation voltage and supports data rates up to 25Mbps. The device operates on a supply voltage of 3V to 5.5V, with a common mode transient immunity (CMTI) of 25kV/µs. It offers a maximum propagation delay of 60ns and functions within a temperature range of -40°C to +105°C. Packaged in a 16-SOIC housing.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power delivery across isolation barriers
• Utilizes iCoupler magnetic coupling technology for high electromagnetic interference immunity
• Features Schmitt trigger inputs to ensure noise rejection and signal integrity
• Provides bidirectional or unidirectional channel configurations with logic-level buffering

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation standards
• Inverter drives and motor control circuits
• Isolated communication interfaces such as RS-485 and CAN bus

Procurement Notes

Verify the specific suffix 'CRWZ-RL' against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with your PCB footprint for the 16-SOIC variant. Cross-reference datasheet revision dates to validate electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when an integrated isolated power supply is required alongside signal isolation to reduce external component count. Consider the 25Mbps data rate and 60ns propagation delay for timing-sensitive applications. Evaluate thermal performance within the -40°C to +105°C operating range for industrial environments.

Part Context

This part belongs to the ADuM640x family of digital isolators, which combines high-speed signal isolation with integrated power conversion. The series is designed to replace traditional optocouplers in applications demanding higher reliability, lower power consumption, and better size efficiency. It leverages silicon dioxide insulation for robust barrier performance.

Replacement Considerations

Check for direct substitutes like the ADUM6401ARWZ-RL, noting differences in temperature grade or packaging if applicable. Verify that any replacement maintains the same 16-SOIC footprint and isoPower functionality to ensure board compatibility without redesign.
