ADUM4400CRIZ

Overview

The ADUM4400CRIZ is a quad-channel digital isolator from Analog Devices, housed in a 16-pin SOIC package. It utilizes magnetic coupling technology to provide electrical isolation with an insulation voltage of 5000 Vrms and supports data rates up to 90 Mb/s. The device operates within a supply voltage range of 2.7 V to 5.5 V and features a typical propagation delay of 32 ns. Designed for unidirectional signal transmission, it offers high common-mode transient immunity and functions reliably across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Provides four independent channels for high-speed digital signal isolation using proprietary magnetic coupling technology.
• Ensures robust safety compliance with 8mm creepage distance and 5000 Vrms insulation rating.
• Integrates Miller clamp functionality to protect connected loads during switching operations.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for patient safety
