I designing an electrochemical sensor readout using Ad5941.The LDO used for powering the ADC is ADM7155.
In the reference design all the capacitors and resistors used are 0603 package.In my design I used all 0805 package.That will make my rework easy.We don't have dedicated lab person.
My first question is,May I know using 0805 package will make any problems in the measurement?
My schematic is given below.Could you please review this schematic,your reviews will help me.
Do I need 4 layers for this board.Space is not a constraint for me.May I know will I be able to make 2 layer board with 2nd layer as dedicated ground plane.
