ADUM221N0BRWZ

Overview

The ADUM221N0BRWZ is a dual-channel digital isolator utilizing iCoupler technology, housed in a 16-pin SOIC package. It provides robust isolation with a rated insulation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, featuring low power consumption and high common-mode transient immunity. It includes one reverse channel for bidirectional communication support within the dual-channel architecture.

Feature Summary

• Dual-channel isolation with integrated reverse channel capability
• High-speed data transmission supporting up to 150 Mb/s
• Robust magnetic coupling technology for reliable signal integrity

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring interfaces

Procurement Notes

Verify the specific suffix (e.g., -RL for reel packaging) against your assembly requirements. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability may vary by region. Ensure the selected variant matches your board layout and volume needs.

Selection Notes

Select this component when dual-channel isolation with a reverse feedback path is required. Compare propagation delay and power consumption against other iCoupler variants if lower latency or reduced current draw is critical. Ensure the 16-pin SOIC footprint fits your design constraints.

Part Context

This part belongs to the ADuM22xN family of dual-channel digital isolators. It shares architectural similarities with the ADUM220N and ADUM225N but offers specific configuration options for reverse channel usage. The series is designed for general-purpose isolation applications requiring high reliability.

Replacement Considerations

Direct substitutes include ADUM220N0BRWZ and ADUM225N0BRWZ. Verify pin compatibility and specific electrical characteristics such as propagation delay and operating temperature range before substitution.
