The analog input model of the 12-bit A/D converter is
shown in
A/D is a function of the internal amplifier settling time
and the holding capacitor charge time.
For the A/D converter to meet its specified accuracy,
the Charge Holding Capacitor (C

The combined impedance of the analog sources must
therefore be small enough to fully charge the holding
capacitor within the chosen sample time. To minimize
the effects of pin leakage currents on the accuracy of
the A/D converter, the maximum recommended source

be completed prior to starting the conversion. The inter-
