Description

Product Overview

The ADuM1301ARWZ from Analog Devices is a triple-channel digital isolator based on iCoupler technology with three independent isolation channels (2 forward, 1 reverse). Providing 2500 Vrms isolation rating, 50 ns max propagation delay, and 90 Mbps data rate, it replaces optocouplers with superior performance, lower power, and higher reliability. Packaged in SOIC-16W for standard PCB assembly.

  • Industrial process control I/O isolation

The ADuM1301ARWZ from Analog Devices is a triple-channel digital isolator using iCoupler technology with 2500 Vrms isolation, 90 Mbps data rate, and 50 ns propagation delay. With 2 forward and 1 reverse channels, it provides bidirectional isolation for SPI, UART, and other communication interfaces. The chip-scale transformer isolation eliminates optocoupler degradation while offering higher speed, lower power, and better CMTI (>25 kV/µs) in a SOIC-16W package.

The ADuM1301ARWZ uses Analog Devices’ iCoupler technology, which integrates microscale on-chip transformers fabricated directly on the semiconductor die. Data signals are modulated and transmitted across the isolation barrier as electromagnetic pulses through the transformers, then demodulated on the receiving side. Unlike optocouplers that rely on LED-phototransistor coupling (which degrades over time and has limited bandwidth), iCoupler technology provides consistent performance, no LED wear-out, and much higher data rates. Each of the three channels operates independently with separate encoding/decoding circuitry. The on-chip refresh circuit continuously updates the output state even when no input transitions occur, ensuring DC correctness across the isolation barrier.
