Product details
The ADuM141x is based on Analog Devices' iCoupler® technology
Quad digital isolator。 These isolation devices combine high-speed CMOS with monolithic air-core transformer technology to provide superior performance characteristics over alternative devices such as optocouplers.
iCoupler devices do not require LEDs and photodiodes, so there are no design difficulties typically associated with optocouplers. The simple iCoupler digital interface and robust performance characteristics eliminate the uncertain current transfer ratio, nonlinear transfer function, and temperature and lifetime effects typically associated with optocouplers. These iCoupler products do not require external drivers and other discrete components. In addition, iCoupler devices consume only 1/10 to 1/6 of the power consumption of optocouplers at comparable signal data rates.
The ADuM141x isolator provides four independent isolation channels, supporting multiple channel configurations and data rates up to 10 Mbps (refer to the Ordering Guide). All models operate from supply voltages from 2.7 V to 5.5 V, are compatible with low-voltage systems, and are capable of voltage conversion across the isolation barrier. All products have default output control pins. This pin allows the user to define the logic state of the output when there is no input supply. Unlike other optocouplers, the ADuM141x isolator has a patented refresh feature that ensures dc correctness in the absence of input logic transitions and power-up/shutdown conditions.
