Input Selection
Window Function
The Analog comparators have a very flexible input selection and the two comparators grouped
in a pair may be used to realize a window function. One pair of analog comparators is shown in
Figure 24-1 on page
•
•
•
The window function is realized by connecting the external inputs of the two analog comparators
in a pair as shown in
Figure 24-2. Analog comparator window function
Input selection from pin
Internal signals available on positive analog comparator inputs
Internal signals available on negative analog comparator inputs
– Pin 0, 1, 2, 3, 4, 5, 6 selectable to positive input of analog comparator
– Pin 0, 1, 3, 5, 7 selectable to negative input of analog comparator
– 64-level scaler of the VCC, available on negative analog comparator input
– Bandgap voltage reference
