Table 3. A/D Timing Configuration for 10-bit Mode
A/D Inputs
In order to obtain accurate measurements with the A/D Converter,
the source drive must be sufficient to adequately charge the
sampling capacitor during the sampling time. Figure 4 shows the
equivalent resistance and capacitance related to the A/D inputs.
A/D timing configurations indicated in Table 1 allow for full A/D
