15.5.3
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input when the A/D conversion start delay time (t
starts conversion. Figure 15.5 shows the A/D conversion timing. Tables 15.3 and 15.4 show the
A/D conversion time.
As indicated in figure 15.5, the A/D conversion time (t
time (t
total conversion time therefore varies within the ranges indicated in table 15.4.
In scan mode, the values given in table 15.4 apply to the first conversion time. The values given in
table 15.3 apply to the second and subsequent conversions.
