Typical Applications
1.0 Half-wave Rectifier with Rail-To-Ground Output
Swing
Since the LMV921 input common mode range includes both
positive and negative supply rails and the output can also
swing to either supply, achieving half-wave rectifier functions
in either direction is an easy task. All that is needed are two
external resistors; there is no need for diodes or matched re-
sistors. The half wave rectifier can have either positive or
negative going outputs, depending on the way the circuit is
arranged.
In Figure 5the circuit is referenced to ground, while in Figure
6the circuit is biased to the positive supply. These configura-
tions implement the half wave rectifier since the LMV921 can
not respond to one-half of the incoming waveform. It can not
respond to one-half of the incoming because the amplifier
can not swing the output beyond either rail therefore the out-
put disengages during this half cycle. During the other half
cycle, however, the amplifier achieves a half wave that can
have a peak equal to the total supply voltage. R
I
should be
large enough not to load the LMV921.
