The ADuM1200-EP is a dual-channel, digital isolator based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technologies,this isolation component provides 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 one-tenth to one-sixth the power of optocouplers at comparable signal data rates.

The ADuM1200-EP isolator provides two independent isolation channels with a supply voltage on either side ranging from 3.0 V to 5.5 V. In addition, the ADuM1200-EP provides low pulse width distortion and tight channel-to-channel matching. Unlike other optocoupler alternatives, the ADuM1200-EP isolator has a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/ power-down conditions.

Full details about this enhanced product are available in the ADuM1200/ADuM1201 data sheet, which should be consulted in conjunction with this data sheet.
