11.8 Internal Equivalent Circuit
The following figure shows the equivalent circuit of the analog input block.
Remarks 1. The maximum values are shown (reference values).
Caution A/D converters 0 and 1 perform the first sampling when A/D conversion starts after A/D
initialization. Sampling power is almost fully charged during this period. Therefore, the
sampling error can be calculated under this condition. After that, the converters perform the
second sampling to correct the error.
The sampling period of A/D converters 0 and 1 is from the start of conversion to the end of the
second sampling period. Avoid noise during this period.
