ADUM221N0WBRWZ

Overview

The ADUM221N0WBRWZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two forward channels with no reverse channel, providing robust isolation rated at 5.0 kVrms and a 7.8mm creepage distance. The device supports data rates up to 150 Mb/s with a typical propagation delay of 7.2 ns. It operates on a single power supply ranging from 1.7 V to 5.5 V, drawing approximately 5.9 mA per channel. Packaged in a wide-body SOIC-16 (W) for enhanced safety clearance, it functions within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Robust 5.0 kVrms insulation voltage with 7.8mm creepage distance for high-voltage isolation
• High-speed bidirectional communication capability supporting up to 150 Mb/s data rates
• Low power consumption design operating on a single supply voltage between 1.7 V and 5.5 V
• Wide-body SOIC-16 package optimized for safety standards and thermal performance

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced isolation barriers
• Power metering and energy management interfaces
• Inverter and motor control circuitry

Procurement Notes

Verify the specific suffix WBRWZ against the manufacturer's latest datasheet to confirm pinout and packaging details. Check current availability status as distribution may be limited or subject to allocation. Ensure compliance with RoHS directives and moisture sensitivity levels before integration into production workflows.

Selection Notes

Select this component when high-speed data transmission is required alongside robust isolation ratings. The wide-body package is suitable for applications demanding increased creepage distances. Consider the 1.7 V minimum supply voltage for compatibility with low-power logic families. Evaluate the 150 Mb/s speed against system timing requirements to ensure signal integrity across the isolation barrier.

Part Context

This part belongs to the ADUM221N series of iCoupler digital isolators. It shares the same core architecture as other variants in the family but differs in channel configuration and packaging. The series is designed to replace traditional optocouplers in high-performance applications, offering superior reliability and lower power consumption while maintaining industry-standard form factors.

Replacement Considerations

Direct substitutes include ADUM221N1BRWZ for configurations requiring a reverse channel. For lower speed requirements, the ADUM2201 series offers comparable isolation with reduced data rates. Verify pin compatibility and electrical specifications before swapping components to ensure system functionality remains intact.
