Hello,
16F882 datasheet specs 10K as max rec. source impedance for the ADC. Also it specs the leakage current as 0.5uA.
With a 5V max input that makes the DC impedance 10Mohms. Thus the 10K limit for a DC analog signal is established by the TAD and not sampling errors due to loading?
Is this reasonable?
thx
