R: The stray capacitance might relatively increase, as the line-distance in between VOUT and A/D gets
longer. If it will be totally 15pF or over, a series resistor ”R” should be used to effectively reduce such
a stray capacitance. R should better be mounted as closely as possible to VOUT, and must be one
thousandth or less of input impedance of A/D. For the reference, R=2k ohm is recommended.
