“+” Input Settling
The input capacitor is switched onto the “+” input during
the sample phase (t
SMPL
, see Figures 8a, 8b and 8c). The
sample period can be as short as t
WHCS
+ 0.5 CLK cycle or
as long as t
WHCS
+ 1.5 CLK cycles before a conversion
starts. This variability depends on where CS falls relative
to CLK. The voltage on the “+” input must settle completely
within the sample period. Minimizing R

will improve the settling time. If large “+” input source

by using a slower CLK frequency. With the minimum
possible sample time of 6.0

“–” Input Settling
At the end of the sample phase the input capacitor switches
to the “–” input and the conversion starts (see Figures 8a,
8b and 8c). During the conversion, the “+” input voltage is
