38.5.1 Principle of Operation
Each comparator has one positive input and one negative input. Each positive input may be chosen from a selection of analog input pins. Each negative input may be chosen from a selection of both analog input pins and internal inputs, such as bandgap voltage reference.
The digital output from the comparator is ‘1
’
when the difference between the positive and the negative input voltage is positive and
‘0
’ otherwise.
The individual comparators can be used independently (Normal mode) or paired to form a window comparison (Window mode).
