The dsPIC30F 10-bit ADC specifications permit a max-
imum 1 Msps sampling rate. Table 18-1 summarizes
the conversion speeds for the dsPIC30F 10-bit ADC
and the required operating conditions.
The configuration guidelines give the required setup
values for the conversion speeds above 500 ksps,
since they require external V
are some differences in the configuration procedure.
Configuration details that are not critical to the
conversion speed have been omitted.
Figure 18-2 depicts the recommended circuit for the
conversion rates above 500 ksps.
