Description
General part information
ADUM7240 Series
The ADuM7240 /ADuM7241are dual channel digital isolators based on the Analog Devices, Inc.,iCoupler®technology. Combining high speed CMOS and monolithic air core trans-former technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler devices and other integrated couplers.The ADuM7240 / ADuM7241 dual 1 kV digital isolation devices are packaged in a narrow-body 8-lead SOIC. The ADuM7240/ ADuM7241 offer a cost-effective option compared to 2.5 kV or 5 kV isolators where only functional isolation is needed.Like other Analog Devices isolators, the ADuM7240 / ADuM7241 offer 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 ADuM7240/ADuM7241 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 ADuM7240 / ADuM7241 provide two 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. The ADuM7240 / ADuM7241 also have an output default high logic state in the absence of input power.APPLICATIONSGeneral-purpose multichannel isolationData converter isolationIndustrial field bus isolation
