Comparator Response Time
(All Comparators)
30mV overdrive (Note 1) 20 µs
Note 1: To overdrive the +5V/+12V/+15V comparators with a 30mV overdrive voltage, use the formula 30mV
to determine the required input voltage. V
THR
is the threshold of the particular overdriven comparator. To overdrive the
-5V/-12V/-15V comparators use 30mV .
