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 8-2. 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
sources is 10 k . After the analog input channel is
selected (changed) this acquisition must be done
before the conversion can be started.

To calculate the minimum acquisition time, T
the
(DS33023). This equation calculates the acquisition
time to within 1/2 LSb error. The 1/2 LSb error is the
maximum error allowed for the A/D to meet its specified
accuracy.
