ADUM2286BRIZ

Overview

The ADUM2286BRIZ is a dual-channel digital isolator manufactured by Analog Devices Inc. It utilizes proprietary CMOS technology to provide high-speed data transmission with electrical isolation between circuits. The device operates at a data rate of 25 Mbps and supports a maximum voltage isolation of 5000 Vrms. It features a default low output configuration and offers common-mode transient immunity of 25 kV/µs. Packaged in a 16-pin SOIC, it is designed for robust performance in noisy environments.

Feature Summary

• Provides galvanic isolation between input and output sides using capacitive coupling technology
• Supports bidirectional data transmission with configurable channel directionality
• Features high common-mode transient immunity to reject noise spikes
• Maintains signal integrity with low propagation delay and pulse width distortion

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation protection
• Power electronics monitoring and control circuits
• Automotive sensor interface modules

Procurement Notes

Verify the specific suffix (e.g., BRIZ vs. BRIZ-RL) to confirm packaging type, as tube and reel variants differ in physical handling requirements. Confirm RoHS compliance status with the manufacturer prior to ordering. Ensure the selected package matches the PCB footprint design. Check regional availability restrictions as distribution may vary by location.

Selection Notes

Select this component when dual-channel isolation is required within a single package to save board space. Consider the 25 Mbps speed limit for application compatibility. Evaluate the 5000 Vrms isolation rating against system safety standards. Compare power consumption metrics if energy efficiency is critical for the design.

Part Context

This part belongs to the ADuM family of digital isolators from Analog Devices. These devices replace traditional optocouplers by offering superior performance characteristics including higher data rates, lower power consumption, and better reliability. The family includes various configurations for different channel counts and isolation voltages.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM series such as the ADUM2281 or ADUM2282. Verify that substitute parts meet the same 5000 Vrms isolation and 25 Mbps speed requirements. Ensure the replacement maintains the default low output logic state if specified by the circuit design.
