For the A/D Converter to meet its specified accuracy,
the charge holding capacitor (C

analog input model is shown in Figure 20-2. The
source impedance (R

at the analog input (due to pin leakage current). The
maximum recommended impedance for analog
sources is 2.5 k. After the analog input channel is
selected (changed), the channel must be sampled for
at least the minimum acquisition time before starting a
conversion.

Equation 20-1 may be used. This equation assumes
that 1/2 LSb error is used (1024 steps for the A/D). The
