The ADuM3300/ADuM3301 are 3-channel digital isolators basedon the Analog Devices, Inc., iCoupler® technology. Combininghigh speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performancecharacteristics superior to alternatives, such as optocoupler devices.
iCoupler devices remove the design difficulties commonly associated with optocouplers. Typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with 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-sixththe power of optocouplers at comparable signal data rates.
The ADuM3300/ADuM3301 isolators provide three independentisolation channels in a variety of channel configurations anddata rates. All models operate with thesupply voltage on either side ranging from 3.3 V to 5.5 V, providingcompatibility with lower voltage systems as well as enabling avoltage translation functionality across the isolation barrier. TheADuM3300/ADuM3301 isolators have a patented refresh featurethat ensures dc correctness in the absence of input logictransitions and during power-up/power-down conditions.
In comparison to ADuM1300/ADuM1301 isolators, ADuM3300/ADuM3301 isolators contain various circuit and layout changesto provide increased capability relative to system-level IEC 61000-4-x testing (ESD, burst, and surge). The precise capabilityin these tests for either the ADuM1300/ADuM1301 orADuM3300/ADuM3301 products is strongly determined by the design and layout of the user’s system.
