ADUM4401WARWZ

Overview

The ADUM4401WARWZ is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features unidirectional data flow with a data rate of 90 Mb/s and an insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical quiescent current of 830 uA per channel. It exhibits a propagation delay of 32 ns and is qualified under AEC-Q100 standards. The component is housed in a 16-lead SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Provides four independent unidirectional channels for high-speed digital isolation using proprietary magnetic coupling technology.
• Offers enhanced electrostatic discharge (ESD) protection capabilities alongside high insulation voltage ratings.
• Delivers low power consumption suitable for battery-operated systems while maintaining high data integrity.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors.
• Medical equipment needing reliable signal isolation for patient safety compliance.
• Automotive electronics adhering to AEC-Q100 qualification standards.

Procurement Notes

Verify the specific suffix WARWZ to confirm the SOIC-16 wide-body package and reel packaging format. Ensure compatibility with AEC-Q100 automotive qualification requirements if used in vehicle applications. Cross-reference datasheet revision levels to confirm pinout consistency with existing designs.

Selection Notes

Select this component when unidirectional signal isolation is required across multiple channels simultaneously. Consider the 90 Mb/s data rate limit and 5000 Vrms insulation rating against system noise immunity needs. Evaluate the 830 uA per channel power consumption against total system budget constraints compared to capacitive alternatives.

Part Context

This part belongs to the ADUM4401 series of digital isolators designed for robust performance in noisy environments. It shares the SOIC-16 footprint with other variants but differs in channel count and directionality. The series emphasizes reliability through magnetic coupling rather than capacitive or optical methods.

Replacement Considerations

ADUM4402WARWZ offers bidirectional capability instead of unidirectional. ADUM4401CRIZ provides the same electrical specifications but utilizes a narrower SOIC-16 package instead of the wide-body variant.
