ADUM1200ARZ Digital Isolators by Analog Devices Inc./Maxim Integrated

The ADUM1200ARZ isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). Both devices operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADUM1200ARZ provide low pulse width distortion (<3 ns for CR grade) and tight channelto-channel matching (<3 ns for CR grade). Unlike other optocoupler alternatives, the ADUM1200ARZ isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during powerup/power-down conditions.
