The analog input model of the 12-bit A/D converter
is shown inFigure 19-4. The total sampling time for the
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

pin. The source impedance (R

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 con-
verter, the maximum recommended source imped-

completed prior to starting the conversion. The internal
