ADUM261N1BRIZ

Digital Isolators Overview

The ADUM261N1BRIZ is a six-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides robust isolation with a rated insulation voltage of 5000 Vrms and a minimum common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s with a typical propagation delay of 7.2 ns. It features five unidirectional input channels on one side and one on the other, operating within a supply voltage range of 1.7 V to 5.5 V. Designed for surface-mount installation in a 16-SOIC package, it functions reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates six independent digital isolation channels using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Delivers high common-mode transient immunity of 75 kV/µs to maintain signal integrity in electrically noisy environments.
• Supports bidirectional power delivery through integrated isolated DC-DC converter capability when paired with external components.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral interfaces.
• Medical equipment needing reliable isolation for patient-connected monitoring circuits.
• Power electronics control loops involving high-voltage switching signals.

Digital Isolators Procurement Notes

Verify the specific suffix (RL) against the manufacturer's current datasheet to confirm packaging configuration. Confirm RoHS compliance status directly with Analog Devices or authorized distributors. Ensure the 16-SOIC footprint matches your PCB design constraints. Check for any recent lifecycle notices regarding obsolescence or alternative recommendations.

Digital Isolators Selection Notes

Select this component when six isolated channels are required in a single package. The 5000 Vrms rating suits applications demanding high dielectric strength. Consider the 150 Mb/s speed limit for high-frequency digital signals. The 16-SOIC package offers a compact solution for space-constrained designs compared to discrete isolation solutions.

Digital Isolators Part Context

This part belongs to the ADuM26xN family of six-channel digital isolators from Analog Devices. These devices leverage silicon dioxide-based transformer technology to provide isolation without optical components. The family includes variants with different channel configurations and power delivery options, all sharing the same core magnetic coupling architecture.

Digital Isolators Replacement Considerations

Check for ADUM261N1BRIZ-RL as the reel-packaged equivalent. Verify if ADUM261N1BRZ is available as the tube-packaged version. No direct pin-compatible replacements from other manufacturers are confirmed in public documentation.
