By using this simplified circuit, the trip voltage can be
calculated using the following equation:

Reasonable capacitive loads (e.g., logic gates) have
little impact on the propagation delay (see

capacitive loads. The output slew rate and propagation
delay performance will be reduced with higher capaci-
tive loads.
4.5.2
The reference output is designed to interface to the
comparator input pins, either directly or with some
resistive network, such as voltage divider network, with
minimal capacitive load. The recommended capacitive
load is 200 pF (typical). Capacitive loads greater than
2000 pF may cause the V
