ADUM3401ARWZ

Overview

The ADUM3401ARWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports bidirectional data transmission at speeds up to 1 Mb/s. The device provides an isolation voltage of 2500 Vrms with a typical propagation delay of 100 ns. It features low power consumption, drawing 1.6 mA on one side and 2.5 mA on the other. The component is housed in a 16-lead SOIC_W package and functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent digital channels using iCoupler magnetic coupling technology for high-speed signal isolation.
• Provides robust system-level ESD reliability and common-mode transient immunity without requiring external components.
• Supports bidirectional data flow with low power consumption suitable for energy-efficient designs.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripherals.
• Medical equipment interfaces needing high isolation voltage for patient safety compliance.
• Power electronics control circuits isolating gate drivers from logic controllers.

Procurement Notes

Verify availability status as distribution channels may indicate limited stock or restricted supply conditions. Confirm the specific suffix ARWZ corresponds to the tube packaging variant rather than reel options. Ensure compatibility with existing PCB footprints for the 16-lead SOIC package before finalizing procurement decisions.

Selection Notes

Select this component when four isolated channels are required within a single package to save board space. Choose the ARWZ variant specifically if tube packaging is preferred over reel or cut-tape formats. Ensure the design requires bidirectional communication capabilities and operates within the specified 2.7 V to 5.5 V voltage range.

Part Context

This part belongs to the ADuM3400/ADuM3401/ADuM3402 family of quad-channel digital isolators. These devices combine high-speed CMOS circuitry with monolithic air-core transformer technology. This integration allows for superior performance compared to traditional optocouplers while maintaining compact form factors suitable for dense electronic assemblies.

Replacement Considerations

Cross-reference with ADUM3401CRWZ for higher speed variants or ADUM3401BRWZ for alternative grade specifications. Verify pinout compatibility and thermal characteristics when substituting to ensure seamless integration into existing designs without hardware modifications.
