ANALOG DEVICES ADUM1201ARZ-RL7 Dual-Channel Digital Isolator

ANALOG DEVICES ADUM1201ARZ-RL7 Product Overview

The ADUM1201ARZ-RL7 is a dual-channel digital isolator from Analog Devices, based on the proprietary iCoupler® technology that combines high-speed CMOS and monolithic transformer technology . It provides two independent isolation channels in a 1/1 channel directionality configuration, making it ideal for applications requiring bidirectional communication across an isolation barrier .

The device offers 2500Vrms galvanic isolation per UL 1577, with a high common-mode transient immunity of 25kV/µs to ensure reliable operation in electrically noisy environments . Operating from a supply voltage of 2.7V to 5.5V, it supports 3V/5V level translation, enabling voltage conversion across the isolation barrier . The device features a data rate of 1Mbps with propagation delay of 150ns maximum and pulse width distortion of 40ns maximum . Operating temperature range is -40°C to +105°C . Housed in an 8-pin SOIC package (3.90mm width), the -RL7 suffix indicates tape and reel packaging with 1000 units per reel . Moisture sensitivity level is MSL 1 (unlimited floor life) .

DEVICES ADUM1201ARZ-RL7 Key Advantages

The ADUM1201ARZ-RL7 employs iCoupler® technology, which eliminates design challenges associated with optocouplers, such as uncertain current transfer ratios, nonlinear transfer functions, and lifetime/temperature effects . iCoupler devices consume significantly lower power — approximately 1/10 to 1/6 of optocoupler equivalents at comparable data rates .

The 1/1 channel configuration provides one forward and one reverse channel, enabling compact bidirectional communication without additional components . The patented refresh feature ensures DC correctness in the absence of input logic transitions and during power-up/power-down conditions .

The wide supply voltage range from 2.7V to 5.5V provides compatibility with both 3V and 5V systems, simplifying interfacing across different logic levels . The high common-mode transient immunity of 25kV/µs ensures robust performance in industrial environments with high electrical noise . The device is approved under UL, CSA, and VDE safety standards .
