I want to get differential output with ADC3442EVM.
Signal input is possible through J1, J4, J5, and J8.
However, it seems that the input does not go through J2, J3, J6, J7.
When I want to give differential input, should I change R11->R8, R25 ->R23, R38->R36, R53->R50?
(In addition, I wonder what the value of this resistor is.)
Second, how do I modify the ADC when I want to do AC coupling? (The board in the manual doesn't seem to include the ADC3442EVM board)
