consumes less power when in a logic low output state.

8.2.2.2 Input Supply Capacitor

Although an input capacitor is not required for stability, for good analog design practice, connect a 100 nF low

equivalent series resistance (ESR) capacitor from (V+) to (V-).

8.2.2.3 Sense Capacitor

Although not required in most cases, for extremely noisy applications, place a 1 nF to 100 nF bypass capacitor

from the comparator input (IN) to the (V-) for good analog design practice. This capacitor placement reduces

device sensitivity to transients.

8.3 What to Do and What Not to Do

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
