Hot-selling and scarce ADUM3402CRWZ Quad-Channel, Digital Isolators SOP16 spot stock

Product Descriptions

The ADuM340x ¹  are 4-channel digital isolators based onAnalog Devices’ iCoupler® technology. Combining high speedCMOS and monolithic air core transformer technology,theseisolation components provide outstanding performancecharacteristics superior to alternatives such as optocoupler devices .

iCoupler devices remove the design difficulties commonlyassociated with optocouplers . Typical optocoupler concernsregarding uncertain current transfer ratios, nonlinear transferfunctions, and temperature and lifetime effects are eliminatedwith the simple iCoupler digital interfaces and stable performancecharacteristics . The need for external drivers and other discretecomponents is eliminated with these iCoupler products .Furthermore, iCoupler devices consume one-tenth to one-sixth thepower of optocouplers at comparable signal data rates .

The ADuM340x isolators provide three independent isolationchannels in a variety of channel configurations and data rates(see the Ordering Guide). All models operate with the supplyvoltage on either side ranging from 2.7 V to 5.5 V, providingcompatibility with lower voltage systems as well as enabling avoltage translation functionality across the isolation barrier. TheADuM340x isolators have a patented refresh feature that ensures dccorrectness in the absence of input logic transitions and duringpower-up/power-down conditions.
