Hi
i am interfacing CD4067BE multiplexer IC with pic micro controller but there is a signal drop of 1.45 volt across the mux . I dont want that and want full signal on input of adc of microcontroller. i think it is due no miss matching of impedences/ is it how can i solve this problem ? Please reply fast as soon as possible if any one can?
Looks like this is abnormal behavior..Generally there will not be huge drop with impedance mismatch .Looks like problem is something else.please check the circuit once again.
