Error from junction leakage is a function of external source impedance and input leakage current. In the following
expression, expected error in result value due to junction leakage is expressed in voltage (V
where I
Charge-sharing leakage is a function of input source impedance, conversion rate, change in voltage between
successive conversions, and the size of the decoupling capacitor used. Error levels are best determined
empirically. In general, continuous conversion of the same channel may not be compatible with high source
impedance.
