TYPICAL SINGLE-SUPPLY APPLICATIONS
Transducer Interface Circuits
Figure 50. Photo Detector Circuit
Photocells can be used in portable light measuring instruments. The LMC6462, which can be operated off a
battery, is an excellent choice for this circuit because of its very low input current and offset voltage.
LMC6462 as a Comparator
Figure 51. Comparator with Hysteresis
Figure 51 shows the application of the LMC6462 as a comparator. The hysteresis is determined by the ratio of
the two resistors. The LMC6462 can thus be used as a micropower comparator, in applications where the
quiescent current is an important parameter.
