PIC17C7XX
Figure 16-2 shows the conversion sequence and the
terms that are used. Acquisition time is the time that the
A/D module’s holding capacitor is connected to the
external voltage level. Then, there is the conversion
time of 12 T
The sum of these two times is the sampling time. There
is a minimum acquisition time to ensure that the holding
capacitor is charged to a level that will give the desired
accuracy for the A/D conversion.
