ADUM2201WBRWZ-RL

Digital Isolators Overview

The ADUM2201WBRWZ-RL is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a rated insulation voltage of 5000 Vrms and a data rate of 10 Mb/s. The device operates on a single supply voltage ranging from 1.7 V to 5.5 V, drawing a typical quiescent current of 800 uA per channel. It features a propagation delay of 50 ns and functions within an operating temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC (Wide) surface-mount format, it ensures robust performance in high-noise environments.

Digital Isolators Feature Summary

• Integrates two independent unidirectional channels for simultaneous signal transmission across isolation barriers.
• Employs on-chip miniaturized transformers to provide galvanic isolation without external components.
• Offers enhanced electromagnetic interference immunity compared to traditional optical couplers.
• Supports wide supply voltage operation suitable for diverse logic families.

Digital Isolators Applications

• Industrial process control systems requiring isolated communication interfaces
• Medical equipment needing patient isolation protection
• Power metering applications with high-voltage sensing requirements

Digital Isolators Procurement Notes

Verify the specific suffix WBRWZ-RL against official Analog Devices documentation to confirm package type and reel configuration. Confirm availability status as distribution listings may indicate limited stock or discontinuation phases. Ensure compliance with RoHS directives and check for any recent product change notices affecting assembly sites or materials before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high-speed digital isolation is required alongside low power consumption. The 10 Mb/s data rate suits general-purpose serial communications like SPI or I2C. Consider the 16-pin SOIC-W package for PCB layout constraints. Verify that the 5000 Vrms insulation rating meets the safety standards of the target application environment.

Digital Isolators Part Context

This part belongs to the ADuM2201 series of dual-channel digital isolators from Analog Devices. It utilizes iCoupler technology, which integrates transformer windings onto silicon substrates. This family replaces legacy optocouplers by offering superior speed, lower power, and better consistency. The series is designed for applications demanding reliable signal transmission across electrical isolation boundaries.

Digital Isolators Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM220x family, such as the ADUM2201ARIZ-RL for tape-and-reel packaging variations. Verify if higher speed variants like the ADUM221N series are acceptable if data rate requirements exceed 10 Mb/s. Ensure substitute parts maintain the same 16-pin SOIC-W footprint and thermal characteristics.
