    high impedance analog pin

    content.librarian

       Hi, Im giving variable analog input(max rating 5V) to PSoC 5lp in high impedance mode.Now my question is can I directly give the potentiometer input to PSoC?How much resistance does any analog pin provide in this mode? Will the current damage PSoC? 

         

      Right now as precaution i have connected 1k in series with POT,Psoc is taking floating value when i switch the input near to zero volts.The reason being psoc is unable to detect ground because of that 1k ohm.
