ADUM1402BRW

Overview

The ADUM1402BRW is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation with a data rate of 10Mbps and a common-mode transient immunity of 25kV/µs. The device operates on a 2.7V to 5.5V supply, features unidirectional channels in a 16-SOIC package, and supports an operating temperature range of -40°C to 105°C.

Feature Summary

• Integrates four independent digital isolation channels within a single compact package.
• Employs iCoupler magnetic coupling technology for galvanic isolation without transformers or optocouplers.
• Provides high common-mode transient immunity to protect against noise spikes.
• Supports standard CMOS logic levels across the isolation barrier.

Applications

• Industrial automation systems requiring signal isolation
• Medical equipment needing patient safety isolation
• Power management circuits with isolated feedback loops
