ADUM2281BRIZ

Overview

The ADUM2281BRIZ is a dual-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage with a common-mode transient immunity of 25kV/µs. The device supports data rates up to 25Mbps and operates on a single supply voltage ranging from 2.7V to 5.5V. It features a propagation delay of 2ns typical and is housed in a 16-SOIC package.

Feature Summary

• High-speed data transmission capability up to 25Mbps for efficient signal integrity
• Robust isolation performance with 5000Vrms rating and high common-mode transient immunity
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Power metering applications with high-voltage separation needs

Procurement Notes

Verify the specific suffix 'BRIZ' against official Analog Devices documentation to confirm pinout, packaging, and electrical characteristics match project requirements. Ensure compliance with RoHS standards and check current availability status as distribution may vary by region.

Selection Notes

Select this component when high-speed bidirectional communication is required alongside robust isolation. Compare against lower speed variants like the ADUM2281ARIZ if bandwidth constraints exist. Confirm that the 16-SOIC footprint fits the PCB layout and thermal management strategy.

Part Context

This part belongs to the ADUM228x series of small, dual-channel digital isolators. It complements other iCoupler products by offering higher data rates compared to standard versions while maintaining compact form factors suitable for space-constrained designs.

Replacement Considerations

The ADUM2281ARIZ serves as a lower-speed alternative within the same family. Verify functional compatibility regarding channel directionality and supply voltage ranges before substitution.
