ADUM1201ARZ Magnetic Isolator Module Instead of The photocoupler MCU1201 ADUM-1201

ADUM1201ARZ Magnetic Isolator Module – Dual Channel Digital Isolator

The ADUM1201ARZ Magnetic Isolator Module is a compact digital signal isolation module based on the ADuM1201 magnetic isolation technology from Analog Devices. It provides reliable electrical isolation between two circuits while allowing digital signals to pass across the isolation barrier.

This module is suitable for isolating microcontrollers, Arduino, ESP32, Raspberry Pi, UART, SPI, RS-232/RS-485 interfaces, industrial control systems, and other digital communication circuits where protection from voltage differences, ground loops, and electrical noise is required.

Important Note

The ADUM1201 is a digital isolator, not a conventional optocoupler. It uses magnetic coupling technology to transfer digital signals across an isolation barrier, providing galvanic isolation between the two sides.

Ideal for projects where two digital circuits need to communicate while remaining electrically isolated from each other.
