ADI ADUM1200UR-EP-RL7

The ADuM1200-EP is a dual-channel digital isolator based on Analog Devices, Inc. iCoupler technology. Combining high-speed CMOS and monolithic transformer technology, this isolation component delivers superior performance over alternatives such as optocouplers. By eliminating LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The straightforward digital interface and stable performance characteristics of iCoupler eliminate common optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. These iCoupler products eliminate the need for external drivers and other discrete components. Furthermore, at comparable signal data rates, iCoupler devices consume one-sixth to one-tenth the power of optocouplers. The ADuM1200-EP isolator provides two independent isolated channels with supply voltage ranges of 3.0 V to 5.5 V on both sides. In addition, the ADuM1200-EP offers low pulse width distortion and tight channel-to-channel matching. Unlike other optocoupler alternatives, the ADuM1200-EP isolator features a patented refresh function that ensures DC correctness in the absence of input logic transitions and during power on/off conditions.
