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 27-1 on page

•
The window function is realized by connecting the external inputs of the two analog comparators
in a pair as shown in
