The worst case occurs when the extremities of the input range (0V and VREF) are sampled consecutively.

In this situation a sampling error below ¼ LSB is ensured by using the following equation:

margin should be considered due to the pin/pad parasitic capacitances, which are not accounted for

in this simple model.

If, in a system where this A/D Converter is used, there are no rail-to-rail input voltage variations between

consecutive sampling phases, Rs may be larger than the value indicated by the equation above.
