The ADuM7240/ADuM7241 are 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 the alternatives, such as optocoupler devices and other integrated couplers.
ADuM724x are 2-channel (dual) isolators 1 kV digital isolation devices is packaged in a narrow-body 8-lead SOIC. The ADuM724x offers a cost effective option compared to 2.5 kV or 5 kV isolators where only functional isolation is needed.
This family, like many Analog Devices isolators, offers very low power consumption, consuming one-tenth to one-sixth the power of comparable isolators at data rates up to 25 Mbps. Despite the low power consumption, all models of the ADuM724x provide low pulse width distortion (<5 ns for C grade). In addition, every model has an input glitch filter to protect against extraneous noise disturbances.
The two channels of ADuM724x are independent isolation channels and are available in two channel configurations with 1 Mbps or 25 Mbps data rates (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. All products also have an output default high logic state in the absence of the input power.
