“–” Input Settling
At the end of the sample phase the input capacitor switches
to the “–” input and the conversion starts (see Figures 11a,
11b, 11c and 12). During the conversion, the “+” input
voltage is effectively “held” by the sample-and-hold and
will not affect the conversion result. It is critical that the
