The ADUM1200ARZ is a dual-channel Digital Isolator based on the Analogue Devices, Inc., iCoupler? technology. Combining high speed CMOS and monolithic transformer technologies, this isolation component provides an outstanding performance characteristics superior to alternatives, such as optocouplers. 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 1/10th to 1/6th the power of optocouplers at comparable signal data rates.
