ADuM130x是采用ADI公司
iCoupler®技术的三通道数字隔离器。这些隔离器件将高速CMOS与单芯片变压器技术融为一体，具有优于光耦合器等替代器件的出色性能特征。
iCoupler devices do not use LEDs and photodiodes, so there are no design difficulties typically associated with optocouplers. The simple i-digital interface and stable performance characteristics eliminate the problems commonly associated with optocouplers, such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and service life effects. These iCoupler products do not require external drivers and other discrete devices. In addition, the iCoupler device consumes only 1/10 to 1/6 the power of an optocoupler at a comparable signal data rate.
The ADuM130x isolator provides three independent isolation channels that support multiple channel configurations and data rates (see the "Ordering Guide" section of the datasheet). Both models operate from a 2.7 V to 5.5 V supply voltage, are compatible with low-voltage systems, and can achieve voltage conversion across isolation barriers. In addition, the ADuM130x features low pulse width distortion (CRW level less than 2 ns) and tight channel-to-channel matching (CRW level less than 2 ns). Unlike other optocouplers, the ADuM130x isolator has a patented refresh feature that ensures DC correctness in the absence of input logic conversion and in the absence of a power supply.
