14.4.3
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input at a time t
conversion timing. Table 14.4 indicates the A/D conversion time.
As indicated in figure 14.5, the A/D conversion time includes t
length of t
time therefore varies within the ranges indicated in table 14.4.
In scan mode, the values given in table 14.4 apply to the first conversion time. In the second and
subsequent conversions the conversion time is as shown in table 14.5.
