GENERAL DESCRIPTION ADUM7240ARZ
The ADuM7240/ADuM72411 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.
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.
