ADUM1201 Dual-Channel Digital Isolator Module

The ADUM1201 Dual-Channel Digital Isolator Module is a high-performance, magnetic galvanic isolation board designed to protect sensitive microcontrollers and logic circuits from high-voltage spikes, ground loops, and electrical noise. Utilizing Analog Devices' patented iCoupler technology, this module replaces traditional optocouplers, offering superior reliability, lower power consumption, and significantly higher data rates. It is an essential component for engineers and makers building robust industrial, automotive, or robotic systems.

This module features a 1/1 bidirectional channel configuration (one transmit channel and one receive channel), making it ideal for isolating serial communication lines such as UART (TX/RX), SPI, and CAN Bus transceivers. With independent power supplies required for both sides (VDD1 and VDD2), it ensures complete electrical isolation between your controller (like an Arduino, ESP32, or Raspberry Pi) and the target peripheral. The breadboard-friendly "Short Version" layout makes prototyping quick and hassle-free.

Features:

• Patented iCoupler Technology: Uses magnetic isolation instead of optical LEDs, ensuring longer life and higher reliability.
• Bidirectional Communication: Dual-channel configuration with 1 forward and 1 reverse channel, perfect for TX/RX serial lines.
• Wide Supply Range: Supports independent 2.7V to 5.5V logic levels on both side 1 and side 2.
• High-Speed Data Transfer: Capable of handling high-speed digital signals up to 25 Mbps.
• Excellent Transient Immunity: Provides high common-mode transient immunity (>25 kV/µs) to prevent signal corruption.
• Compact & Breadboard Friendly: Small form-factor breakout board with standard 2.54mm pitch headers included.
