Im still working on ATmega16 which has buil-in A/D -converter. It seems that the converter is a drain for 10mA current ( 0 - 5 V ). Devise that feeds the analog voltage gives only 5mA ( 0 - 10 V ). So at the moment when I connect the lines, voltage drops heavily from about 4 V --> some mV.
Is there a way to work it out? 10mA sound quite big to me. Is there a possibility that there are something totally wrong because the current requirement is so big?
