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.
