ADUM3402ARWZ-RL

Overview

The ADUM3402ARWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a data rate of 1 Mb/s and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming approximately 2 mA of working power current. It features a propagation delay of 100 ns and rise/fall times of 3 ns. The component is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent bidirectional channels for comprehensive signal isolation
• Employs monolithic air-core transformer technology for high-speed digital communication
• Provides robust galvanic isolation between separate circuit domains

Applications

• Industrial process control systems requiring multi-channel isolation
• Medical equipment needing safe patient isolation barriers
