Application Information
Typical Single-Supply Applications
TRANSDUCER INTERFACE CIRCUITS
Photocells can be used in portable light measuring instru-
ments. 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 17 shows the application of the LMC6462 as a com-
parator. 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.
