ADUM3210WARZ

Overview

The ADUM3210WARZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two independent isolation channels with a data rate of 1 Mbps and a maximum propagation delay of 50 ns. The device operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 7.6 mA. It provides an insulation voltage of 2500 Vrms and supports bidirectional signal transmission. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates two independent digital isolation channels using on-chip monolithic transformer technology
• Provides bidirectional signal transmission capability for flexible system configuration
• Eliminates design difficulties associated with optocouplers by avoiding LEDs and photodiodes
• Supports voltage translation functionality between different logic levels across the isolation barrier

Applications

• Automotive electronic control units requiring robust galvanic isolation
• Industrial fieldbus systems needing reliable signal transmission
• Power inverter gate drive circuits
• General-purpose multi-channel isolation interfaces

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with moisture sensitivity level requirements during storage and handling. Confirm that the selected variant meets all necessary automotive qualification standards if deployed in regulated environments.

Selection Notes

Select this component when bidirectional communication is required over a single isolation barrier. Consider the 1 Mbps data rate limit for high-speed applications. Evaluate the SOIC-8 package constraints against available board space. Verify power supply voltage compatibility with the 2.7 V to 5.5 V operational range.

Part Context

This part belongs to the ADUM3210 series of dual-channel digital isolators. It shares the core iCoupler architecture with other variants in the family but differs in channel directionality and data rate specifications. The WARZ suffix indicates a specific tape and reel packaging option suitable for automated surface-mount assembly processes.

Replacement Considerations

ADUM3210ARZ-RL7 serves as a confirmed substitute offering identical electrical characteristics and pinout compatibility.
