The ADuM344x1 are four channel, digital isolators based on the Analog Devices, Inc., iCoupler® technology supporting data rates up to 150 Mbps. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices. By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The 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 performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates. The ADuM344x isolators provide four independent isolation channels in a variety of channel configurations (see the Ordering Guide). The ADuM344x operates with the supply voltage on either side ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. In addition, the ADuM344x provides low pulse width distortion and tight channel-to-channel matching. Unlike other opto- coupler alternatives, the ADuM344x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during the power-up/power-down condition.
