ADUM2250WARWZ

Overview

The ADUM2250WARWZ is a dual-channel digital isolator from Analog Devices, designed for hot-swappable I2C applications. It utilizes magnetic coupling technology to provide robust signal isolation with a rated insulation voltage of 5000 Vrms. The device supports bidirectional data transmission at a maximum data rate of 1 Mb/s and features a common-mode transient immunity of 25 kV/µs. Operating on a supply voltage range of 3V to 5.5V, it is housed in a 16-lead SOIC_W package. The component is qualified under AEC-Q100 standards and functions reliably within an operating temperature range of -40°C to +105°C.

Feature Summary

• Supports hot-swappable operations for I2C bus systems without causing system crashes or data corruption during live insertion.

Applications

• Hot-swappable I2C bus isolation
• Industrial automation control systems
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix WARWZ to confirm the wide-body SOIC package and reel packaging configuration. Ensure compatibility with AEC-Q100 automotive qualification requirements if deploying in vehicle electronics. Confirm moisture sensitivity level handling procedures are followed during assembly to prevent package damage.

Selection Notes

Select this component when bidirectional I2C isolation is required with high thermal stability. The wide operating temperature range suits harsh industrial environments. Verify that the 16-pin footprint fits the PCB layout constraints compared to narrower SOIC packages.

Part Context

This part belongs to the ADuM225x series of digital isolators. It shares the core magnetic coupling architecture with other members but is specifically optimized for bidirectional I2C protocols. The series provides a compact solution for galvanic isolation in mixed-signal circuits.
