I have to measure a battery voltage using LPC1114 ADC. I would like to use a resistor divider to reduce the imput voltage to the ADC pin. The problem I have is I don't know the imput resistance of the pin so I can't design the resistor divider. Can somebody tell me the imput resistance of the LPC1114 ADC pin? Thank you very much.
