For the A/D converter to meet its specified accuracy,
the Charge Holding capacitor (C
to fully charge to the input channel voltage level. The
analog input model is shown in Figure 8-4. The source
impedance (R
impedance directly affect the time required to charge
the capacitor C
impedance varies over the device voltage (V
source impedance affects the offset voltage at the
analog input (due to pin leakage current). The
maximum recommended impedance for analog
sources is 10 k . After the analog input channel is
selected (changed) this acquisition must be done
before the conversion can be started.
