The ADI Chinese version data sheet is a translation of the English version data sheet, which introduces the features and characteristics of the ADuM7440/ADuM7441/ADuM7442 four-channel digital isolators.
The ADuM744x series are four-channel digital isolators utilizing Analog Devices' iCoupler technology, combining high-speed CMOS with monolithic air-core transformer technology. These devices offer superior performance compared to optocouplers and other integrated couplers, featuring a compact 16-lead QSOP package that saves approximately 70% of PCB space while maintaining a 1000 V rms isolation rating. The series supports data rates up to 25 Mbps and operates with 3.0 V to 5.5 V supply voltages. This manual is written in Chinese.
