ADUM3210WARZ-RL7

Overview

The ADUM3210WARZ-RL7 is a dual-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 rates up to 25 Mb/s. The device provides an insulation voltage of 2500 Vrms with a typical propagation delay of 50 ns and a quiescent current of 7.6 mA. It is housed in an SOIC-8 package and is qualified under AEC-Q100 standards for automotive applications, functioning reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates two independent isolation channels using chip-level transformer technology to eliminate LED and photodiode limitations.
• Supports bidirectional signal transmission with voltage translation capabilities across the isolation barrier.
• Provides high common-mode transient immunity and low power consumption compared to traditional optocouplers.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Automotive electronics meeting AEC-Q100 qualification standards
• Isolated gate driver circuits for power management

Procurement Notes

Verify the specific suffix (WBRZ vs WARZ) against the design specification, as variations may exist regarding packaging or regional compliance. Confirm that the SOIC-8 footprint matches the PCB layout requirements. Ensure the bidirectional channel configuration aligns with the system's data flow needs. Check for any recent Product Change Notifications (PCN) affecting manufacturing sites or materials.

Selection Notes

Select this component when bidirectional data transfer is required between isolated domains. The 25 Mb/s rate suits standard industrial protocols like RS-485 or CAN. Consider the 2500 Vrms isolation rating for safety compliance. The AEC-Q100 qualification makes it suitable for automotive environments where thermal stability and reliability are critical constraints.

Part Context

This part belongs to the ADuM3210 series of dual-channel digital isolators. It serves as a modern replacement for optocouplers in applications demanding higher speed, lower power, and greater reliability. The series leverages silicon dioxide insulation barriers to provide robust signal isolation without the degradation issues associated with light-emitting components.

Replacement Considerations

Direct substitutes include other ADuM3210 variants such as ADUM3210ARZ or ADUM3210BRZ, depending on the required channel directionality (unidirectional vs. bidirectional). Verify pin compatibility and isolation voltage ratings before substitution.
