These characteristics are a value at the time of the external part value which was shown in the
external-circuit instance.
(note 1) Be careful an input signal which doesn't cross a power supply voltage in case of the
positive-polarity and large-range. DC direct mode only use normal range, when input is
1.1Vpp, PGA is 30H setting, it will be full scale. (@VCLP voltage=1.1V)
(note 2) When SHR width is minimum.
