Do connect a 100 nF decoupling capacitor from (V+) to (V-) for best system performance.

If the monitored voltage is noisy, do connect a decoupling capacitor from the comparator input (IN) to (V-).

Don't use resistors for the voltage divider that cause the current through them to be less than 100 times the input current of the comparator without also accounting for the impact on accuracy.

Don't use a pull-up resistor that is too small because the larger current sunk by the output may exceed the desired low-level output voltage (V_OL).
