22.6.2
The analog input model of the 10-bit A/D converter is
shown in Figure 22-5. The total acquisition time for the
A/D conversion 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 analog output source impedance (R
interconnect impedance (R

the time required to charge the C
impedance of the analog sources must therefore be
small enough to fully charge the holding capacitor
