Figure 19-2 depicts the recommended circuit for the
conversion rates above 200 ksps. The dsPIC30F3014
is shown as an example.
FIGURE 19-2:
The configuration procedures below give the required
setup values for the conversion speeds above
100 ksps.
19.7.1
The following configuration items are required to
achieve a 200 ksps conversion rate.
• Comply with conditions provided in Table 19-2.
• Connect external V
• Set SSRC<2.0> = 111 in the ADCON1 register to
• Enable automatic sampling by setting the ASAM
• Write the SMPI<3.0> control bits in the ADCON2
