In my application, the reason for the isolation is to prevent interference between the digital and isolated sides as well as to control loop currents. There really is no need to have isolation for safety. The datasheet indicates to void out the area below the isolator body. Would this still be true for my application? We have a complex board, with components on both sides of the board, and limited space. The board is 0.140" thick. Is a void below the middle of the part that is 0.025" wide, and approximately 0.050" deep (no planes, no traces) sufficient to prevent any coupling of the ISO7140 internal oscillator onto the isolated side?
Thanks
