leakage into the pin and on leakage due to charge-sharing with internal capacitance.
Error from junction leakage is a function of external source impedance and input leakage current. Expected
error in result value due to junction leakage is expressed in voltage (V
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.
