ADUM6401ARWZ

Overview

The ADUM6401ARWZ is a quad-channel digital isolator from Analog Devices, featuring an integrated isolated DC-to-DC converter. It provides 5000 Vrms insulation voltage and supports data rates up to 25 Mb/s with a propagation delay of 55 ns. The device operates on a 3 V to 5.5 V supply, consumes 12 mA working current, and functions within a temperature range of -40°C to +105°C. Packaged in a 16-SOIC format, it offers unidirectional signal transmission with magnetic coupling isolation.

Feature Summary

• Integrates an isolated DC-to-DC converter for simplified power management
• Provides high common-mode transient immunity via magnetic coupling technology
• Supports unidirectional data transmission across four independent channels

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced electrical safety barriers
• Power electronics control circuits with high voltage noise environments

Procurement Notes

Verify the specific suffix (e.g., ARWZ) against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and isolation requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when integrated isolated power is required alongside multi-channel signal isolation. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate thermal performance given the internal DC/DC converter's power dissipation characteristics in enclosed applications.

Part Context

This part belongs to the ADUM640x series of digital isolators. It shares architectural similarities with other members like the ADUM6402 but differs in channel directionality and pinout configurations. The series utilizes iCoupler technology for compact, high-performance isolation solutions.

Replacement Considerations

Check official substitution lists for variants such as ADUM6402ARWZ. Verify that alternative parts match the 16-SOIC package and 5kV isolation rating. Confirm functional equivalence regarding the integrated DC/DC converter capabilities.
