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 in-
put 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.
HALF-WAVE AND FULL-WAVE RECTIFIERS
In Figure 18 Figure 19 R
limits current into the amplifier
since excess current can be caused by the input voltage ex-
ceeding the supply voltage.
PRECISION CURRENT SOURCE
The output current I

is given by:
OSCILLATORS
For single supply 5V operation, the output of the circuit will
swing from 0V to 5V. The voltage divider set up R
, R
and
R
will cause the non-inverting input of the LMC6462 to
move from 1.67V (
1
3
of 5V) to 3.33V (
2
3
of 5V). This voltage
behaves as the threshold voltage.
R
and C
determine the time constant of the circuit. The fre-
quency of oscillation, f
