Application Notes
4.9 COMPARATOR WITH HYSTERESIS
The LMV321/358/324 can be used as a low power compara-
tor. Figure 24 shows a comparator with hysteresis. The
hysteresis is determined by the ratio of the two resistors.

The differential voltage at the input of the op amp should not
exceed the specified absolute maximum ratings. For real
comparators that are much faster, we recommend you to use
National’s LMV331/393/339, which are single, dual and quad
general purpose comparators for low voltage operation.
