ADM3260 performance in a two layer PCB

Question

Hello comunity, good morning/afternoon/night to all 
 I saw this question in the forum but the answer was not clear. 
 I want to know if it is possible to intergrate the ADM3260 in a dual layer design. The application I am working on is an isolated PH meter. 
 
 Thanks!!

Hi Javier, 
 It may be possible with very careful layout to meet Class A on a two layer. Best for emissions would be to use a 4-layer board and use the inner layers to create stitching capacitance. 
 There may be an easier way to meet emissions targets on two layer board. The new ADuM5028 is designed to meet Class B emissions on a 2-layer board. Then use the ADuM1250 I2C isolator for the SDA and SCL lines.
