GENERAL DESCRIPTION  
The ADuM7240/ADuM72411 are 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 alterna-  
tives, such as optocoupler devices and other integrated couplers.  
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 configura-  
tions 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.  
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
