ADuM1240 (ADuM1240 - ADuM1246) Dual-Channel Digital Isolators

The ADuM1240/ADuM1241/ADuM1245/ADuM12461 are micropower, dual-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices, yet consu.
