17.5.3
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 17.5 shows the A/D conversion timing. Table 17.3 shows the A/D
conversion time.
As indicated in figure 17.5, the A/D conversion time (t
(t
conversion time therefore varies within the ranges indicated in table 17.3.
In scan mode, the values given in table 17.3 apply to the first conversion time. The values given in
table 17.4 apply to the second and subsequent conversions.
