ADUM4400WARWZ-RL

Overview

The ADUM4400WARWZ-RL is a quad-channel digital isolator from Analog Devices, packaged in a 16-lead SOIC_W. It features magnetic coupling isolation with a rated insulation voltage of 5000 Vrms and supports data rates up to 90 Mb/s. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing a typical operating current of 830 uA. It provides unidirectional signal transmission with a propagation delay of 32 ns and rise/fall times of 3 ns. The component is qualified for AEC-Q100 automotive standards and functions within an extended temperature range of -40°C to +105°C.

Feature Summary

• Provides four independent channels of unidirectional digital signal isolation using magnetic coupling technology.
• Features enhanced ESD protection capabilities alongside high insulation voltage ratings for robust system safety.
• Integrates low-power operation suitable for battery-powered or energy-constrained applications.

Applications

• Automotive infotainment systems requiring isolated communication between domains
• Industrial automation controllers needing reliable signal isolation
• Medical equipment interfaces demanding high safety standards

Procurement Notes

Verify the specific suffix WARWZ-RL against official Analog Devices documentation to confirm package type and reel configuration. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Cross-reference datasheet revisions to validate parameter consistency before integration into final designs.

Selection Notes

Select this component when four isolated unidirectional channels are required with high-speed data transmission up to 90 Mb/s. Consider the 5000 Vrms insulation rating for applications involving significant potential differences. Evaluate power consumption constraints as the device draws 830 uA per channel under typical conditions.

Part Context

This part belongs to the ADUM4400 series of digital isolators, designed for high-reliability applications. It complements other Analog Devices interface solutions by offering integrated isolation without external transformers. The SOIC_W package facilitates surface-mount assembly in compact PCB layouts.
