V
can be tied to ground when A/D converter is not in use: however extra consumption (around 200 uA)
on main V
will occur due to internal analog circuitry not being completely turned off: so, it is
recommended to keep V
DDA
at V
DD
level even when not in use.
V
may exceed V
and V
limits, remaining within absolute maximum ratings, but the results of
the conversion will be clamped respectively to 0x000 or 0x3FF.

During the sample time the input capacitance C
can be charged/discharged by the external source.
The internal resistance of the analog source must allow the capacitance to reach its final voltage level
within t
. After the end of the sample time t
, changes to the analog input voltage have no effect on the
conversion result. Values for the sample clock t
S
depend on programming.
This parameter includes the sample time t
, the time for determining the digital result and the time for
loading the result register with the conversion result.
