ADuM3442 Functional Block Diagram GENERAL DESCRIPTION 1 The ADuM344x are four channel, digital isolators based on the Furthermore, iCoupler devices consume one-tenth to one-sixth Analog Devices, Inc., iCoupler technology supporting data rates the power of optocouplers at comparable signal data rates. up to 150 Mbps. Combining high speed CMOS and monolithic The ADuM344x isolators provide four independent isolation air core transformer technology, these isolation components channels in a variety of channel configurations (see the provide outstanding performance characteristics superior to Ordering Guide). The ADuM344x operates with the supply alternatives such as optocoupler devices. voltage on either side ranging from 3.0 V to 5.5 V, providing By avoiding the use of LEDs and photodiodes, iCoupler compatibility with lower voltage systems as well as enabling devices remove the design difficulties commonly associated voltage translation functionality across the isolation barrier. In with optocouplers. The typical optocoupler concerns regarding addition, the ADuM344x provides low pulse width distortion uncertain current transfer ratios, nonlinear transfer functions, and tight channel-to-channel matching. Unlike other opto- and temperature and lifetime effects are eliminated with the coupler alternatives, the ADuM344x isolators have a patented simple iCoupler digital interfaces and stable performance refresh feature that ensures dc correctness in the absence of characteristics. The need for external drivers and other discrete input logic transitions and during the power-up/power-down components is eliminated with these iCoupler products. condition. 1 Protected by U.S. Patents 5,952,849 6,873,065 6,903,578 and 7,075,329.
