Comparator Operation
Comparator Reference
A single comparator is shown in
levels and the digital output. When the analog input at V
the output of the comparator is a digital low level. When the analog input at V
the analog input V
the output of the comparator in
response time.
An external or internal reference signal may be used depending on the comparator operating
mode. The analog signal that is present at V
output of the comparator is adjusted accordingly
