A single comparator is shown in
the relationship between the analog input levels and
the digital output. When the analog input at V
than the analog input, V
tor is a digital low level. When the analog input at V
is greater than the analog input, V
comparator is a digital high level. The shaded areas of
the output of the comparator in
the uncertainty due to input offsets and response time.

Response time is the minimum time, after selecting a
new reference voltage or input source, before the com-
parator output has a valid level. The response time of
the comparator differs from the settling time of the volt-
age reference. Therefore, both of these times must be
considered when determining the total response to a
comparator input change. Otherwise, the maximum
delay of the comparators should be used (see
Section 31.0 “Electrical Characteristics”
