28.4.4
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input at a time t
shows the A/D conversion timing. Table 28.4 indicates the A/D conversion time.
As indicated in figure 28.6, the A/D conversion time includes t
length of t
time therefore varies within the ranges indicated in table 28.4.
In multi mode and scan mode, the values given in table 28.4 apply to the first conversion. In the
second and subsequent conversions the conversion time is fixed at 536 states when CKS = 0 or
266 states when CKS = 1.
In all cases, the CKS bit in ADCSR should be set according to the frequency of P
conversion time is within the range shown in table 32.16 in section 32, Electrical Characteristics.
