GENERAL DESCRIPTION The ADuM1201 are dual-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technologies, these isolation components provide 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.
