7.2.2 LMC646x as a Comparator

LMC6462 LMC6464 Comparator with Hysteresis Figure 7-14 Comparator with Hysteresis

Figure 7-14 shows the application of the LMC646x as a comparator. The hysteresis is determined by the ratio of the two resistors. The LMC646x can thus be used as a micropower comparator, in applications where the quiescent current is an important parameter.
