ADUM220N0BRWZ

Digital Isolators Overview

The ADUM220N0BRWZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides robust signal isolation with a rated insulation voltage of 5000 Vrms and a creepage distance of 7.8 mm. The device supports data rates up to 150 Mb/s with a common-mode transient immunity of 75 kV/µs. Operating on a single supply voltage between 3 V and 5.5 V, it features two forward channels and zero reverse channels in a unidirectional configuration. Packaged in a 16-lead SOIC (0.295 inch width), it operates within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• High-speed bidirectional or unidirectional data transmission via magnetic coupling
• Robust isolation barrier with high common-mode transient immunity
• Wide operating supply voltage range for flexible system integration

Digital Isolators Applications

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

Digital Isolators Procurement Notes

Verify the specific suffix 'N0' indicates the unidirectional variant with zero reverse channels. Confirm the package type matches the required PCB footprint. Check RoHS compliance status as indicated by the 'Z' suffix. Ensure the datasheet version aligns with current manufacturing specifications. Validate that the 150 Mb/s speed rating meets the application timing requirements.

Digital Isolators Selection Notes

Select this component when high-speed isolation is required alongside robust noise immunity. The unidirectional channel configuration suits applications where signal flow is strictly one-way. Consider the 7.8 mm creepage distance for safety-critical designs. Evaluate power consumption against system thermal constraints. Compare against other ADUM series parts if bidirectional communication is needed later.

Digital Isolators Part Context

This part belongs to the ADUM220 family of digital isolators. It shares the iCoupler technology foundation with other members like the ADUM2200 and ADUM2201. Unlike the ADUM2201 which offers symmetric channels, this variant specifies a 2:0 channel count. It serves as a specialized solution for high-speed, unidirectional isolation tasks within the broader interface IC portfolio.
