A-D CONVERTER
The 4501 Group has a built-in A-D conversion circuit that performs
conversion by 10-bit successive comparison method. Table 11
shows the characteristics of this A-D converter. This A-D converter
can also be used as an 8-bit comparator to compare analog volt-
ages input from the analog input pin with preset values.
