High Compliance Current Sink
A current sink circuit is shown in
quires only one resistor (R
which is directly proportional to this resistor value.
POWER AMPLIFIER
A power amplifier is illustrated in
provide a higher output current because a transistor follower
is added to the output of the op amp.

LED DRIVER
The LMV321/LMV358/LMV324 can be used to drive an LED
as shown in
COMPARATOR WITH HYSTERESIS
The LMV321/LMV358/LMV324 can be used as a low power
comparator.
The hysteresis is determined by the ratio of the two resistors.
where
Since LMV321/LMV358/LMV324 have rail-to-rail output, the
(V
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 use
National's LMV331/LMV93/LMV339, which are single, dual
and quad general purpose comparators for low voltage oper-
ation.
