Analog Devices ADuM124x Dual-Channel Digital Isolators are micropower digital isolators that are based on the Analog Devices 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 consume extremely low power. This series of dual, 3.75kVrms digital isolation devices operate with supplies as low as 2.25V and typically consume a minimal current of less than 6μA per channel at data rates below 20kbps, a fraction of the power of comparable isolators at comparable data rates (up to 2Mbps). In addition, all models provide low pulse width distortion (<8ns) and an input glitch filter for extraneous noise disturbance protection. All models operate with an independent supply voltage on either side (between 2.25V and 3.6V), providing compatibility with lower voltage systems and enabling voltage level translation functionality across the isolation barrier. In the absence of input power, the products default to a predetermined output logic state: the ADuM1240 and ADuM1241 default to high output, and the ADuM1245 and ADuM1246 default to low output.
