ADI ADUM1441ARQZ-RL7

磁耦合42500Vrms

Overview

 The ADUM1441ARQZ-RL7 is a micropower, 4-channel digital isolator which has default high output and 3/1 channel directionality based on the Analog Devices, Inc., iCoupler® technology. (Dual-channel products available). Combining high speed, complementary metal oxide semiconductor (CMOS) and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler devices, while requiring the lowest power of any available isolation product. The ENX signals can be used to disable the internal refresh, which lowers the total quiescent current to less than 1 µA.

Despite the low power consumption, all models of the ADuM1440/ ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 provide low, pulse width distortion <8 ns. In addition, every model has an input glitch filter to protect against extraneous noise disturbances.
