The dsPIC30F 12-bit ADC specifications permit a max-
imum of 200 ksps sampling rate. Table 16-1 summa-
rizes the conversion speeds for the dsPIC30F 12-bit
ADC and the required operating conditions.
Figure 16-2 depicts the recommended circuit for the
conversion rates above 200 ksps. The dsPIC30F2011
is shown as an example.
