So the error due to the voltage partitioning between the real resistive path and C

Equation 16
The other conditions to be verified is the time constants of the transients are really and
significantly shorter than the sampling period duration T
Equation 17
For complete set of parameters characterizing the ST10F272 A/D Converter equivalent
circuit, refer to
Now the three element of the external circuit R
conditions discussed in the previous paragraphs have been used to size the
component, the other must now be verified. The relation which allow to minimize the
accuracy error introduced by the switched capacitance equivalent resistance is in this
case:
