Application Circuits
Basic Comparator
A basic comparator circuit is used for converting analog
signals to a digital output. The LMV331/393/339 have an
open-collector output stage, which requires a pull-up resistor
to a positive supply voltage for the output to switch properly.
When the internal output transistor is off, the output voltage
will be pulled up to the external positive voltage.
The output pull-up resistor should be chosen high enough so
as to avoid excessive power dissipation yet low enough to
supply enough drive to switch whatever load circuitry is used
on the comparator output. On the LMV331/393/339 the
pull-up resistor should range between 1k to 10kΩ.
DS100080-26
The comparator compares the input voltage (Vin) at the
non-inverting pin to the reference voltage (Vref) at the invert-
ing pin. If Vin is less than Vref, the output voltage (Vo) is at the
saturation voltage. On the other hand, if Vin is greater than
Vref, the output voltage (Vo) is at Vcc..
DS100080-4
FIGURE 1. Basic Comparator
Comparator with Hysteresis
The basic comparator configuration may oscillate or produce
a noisy output if the applied differential input voltage is near
the comparator’s offset voltage. This usually happens when
the input signal is moving very slowly across the compara-
tor’s switching threshold. This problem can be prevented by
the addition of hysteresis or positive feedback.
Inverting Comparator with Hysteresis
The inverting comparator with hysteresis requires a three
resistor network that are referenced to the supply voltage Vcc
of the comparator. When Vin at the inverting input is less
than Va, the voltage at the non-inverting node of the com-
<
parator (Vin
Va), the output voltage is high (for simplicity
assume Vo switches as high as Vcc). The three network
resistors can be represented as R1//R3 in series with R2. The
lower input trip voltage Va1 is defined as
When Vin is greater than Va (Vin Va), the output voltage is
low very close to ground. In this case the three network
resistors can be presented as R2//R3 in series with R1. The
upper trip voltage Va2 is defined as
The total hysteresis provided by the network is defined as
∆Va = Va1 - Va2
To assure that the comparator will always switch fully to Vcc
and not be pulled down by the load the resistors values
should be chosen as follow:
<<

and R1 Rpull-up

FIGURE 2. Inverting Comparator with Hysteresis
Non-Inverting Comparator with Hysteresis
Non inverting comparator with hysteresis requires a two
resistor network, and a voltage reference (Vref) at the invert-
ing input. When Vin is low, the output is also low. For the
output to switch from low to high, Vin must rise up to Vin1
where Vin1 is calculated by
When Vin is high, the output is also high, to make the
comparator switch back to it’s low state, Vin must equal Vref
before Va will again equal Vref. Vin can be calculated by:
DS100080-22
The hysteresis of this circuit is the difference between Vin1
and Vin2
.
∆Vin = VccR1/R2

Capacitor C1 must now discharge through R4 towards
ground. The output will return to its high state when the
voltage across the capacitor has discharged to a value equal

Square Wave Oscillator
to Va2
.
Comparators are ideal for oscillator applications. This square
wave generator uses the minimum number of components.
The output frequency is set by the RC time constant of the
capacitor C1 and the resistor in the negative feedback R4.
The maximum frequency is limited only by the large signal
propagation delay of the comparator in addition to any ca-
pacitive loading at the output, which would degrade the
output slew rate.
For the circuit shown, the period for one cycle of oscillation
will be twice the time it takes for a single RC circuit to charge
up to one half of its final value. The time to charge the
capacitor can be calculated from
Where Vmax is the max applied potential across the capaci-
tor = (2Vcc/3)
and VC = Vmax/2 = VCC/3
One period will be given by:
1/freq = 2t
or calculating the exponential gives:
1/freq = 2(0.694) R4 C1
Resistors R3 and R4 must be at least two times larger than
R5 to insure that Vo will go all the way up to Vcc in the high
state. The frequency stability of this circuit should strictly be
a function of the external components.
Free Running Multivibrator
A simple yet very stable oscillator that generates a clock for
slower digital systems can be obtained by using a resonator
as the feedback element. It is similar to the free running
multivibrator, except that the positive feedback is obtained
through a quartz crystal. The circuit oscillates when the
transmission through the crystal is at a maximum, so the
crystal in its series-resonant mode.
DS100080-8
The value of R1 and R2 are equal so that the comparator will
switch symmetrically about +Vcc/2. The RC constant of R3
and C1 is set to be several times greater than the period of
the oscillating frequency, insuring a 50% duty cycle by main-
taining a DC voltage at the inverting input equal to the
absolute average of the output waveform.
When specifying the crystal, be sure to order series resonant
with the desired temperature coefficient
DS100080-24
FIGURE 5. Squarewave Oscillator
To analyze the circuit, assume that the output is initially high.
For this to be true, the voltage at the inverting input Vc has to
be less than the voltage at the non-inverting input Va. For Vc
to be low, the capacitor C1 has to be discharged and will
charge up through the negative feedback resistor R4. When
it has charged up to value equal to the voltage at the positive
input Va1, the comparator output will switch.
Va1 will be given by:
If:
R1 = R2 = R3
Then:
Va1 = 2Vcc/3
DS100080-7
When the output switches to ground, the value of Va is
reduced by the hysteresis network to a value given by:
FIGURE 6. Crystal controlled Oscillator
Va2 = Vcc/3
www.national.com

These terms will have a slight error due to the fact that Vmax
is not exactly equal to 2/3 VCC but is actually reduced by the
diode drop to:
Application Circuits (Continued)
Pulse generator with variable duty cycle:
The pulse generator with variable duty cycle is just a minor
modification of the basic square wave generator. Providing a
separate charge and discharge path for capacitor C1 gener-
ates a variable duty cycle. One path, through R2 and D2 will
charge the capacitor and set the pulse width (t1). The other
path, R1 and D1 will discharge the capacitor and set the time
between pulses (t2).
By varying resistor R1, the time between pulses of the gen-
erator can be changed without changing the pulse width.
Similarly, by varying R2, the pulse width will be altered
without affecting the time between pulses. Both controls will
change the frequency of the generator. The pulse width and
time between pulses can be found from:
Positive Peak Detector:
Positive peak detector is basically the comparator operated
as a unit gain follower with a large holding capacitor from the
output to ground. Additional transistor is added to the output
to provide a low impedance current source. When the output
of the comparator goes high, current is passed through the
transistor to charge up the capacitor. The only discharge
path will be the 1M ohm resistor shunting C1 and any load
that is connected to the output. The decay time can be
altered simply by changing the 1M ohm resistor. The output
should be used through a high impedance follower to a avoid
loading the output of the peak detector.

FIGURE 7. Pulse Generator
DS100080-17
FIGURE 8. Positive Peak Detector
Negative Peak Detector:
For the negative detector, the output transistor of the com-
parator acts as a low impedance current sink. The only
discharge path will be the 1 MΩ resistor and any load
impedance used. Decay time is changed by varying the 1
MΩ resistor
Solving these equations for t1 and t2
t1 =R4C1ln2

FIGURE 10. Driving CMOS
FIGURE 12. AND Gate
OR Gates
A three input OR gate is achieved from the basic AND gate
simply by increasing the resistor value connected from the
inverting input to Vcc, thereby reducing the reference volt-
age.
A logic ″1″ at any of the inputs will produce a logic ″1″ at the
output.
DS100080-6
FIGURE 11. Driving TTL
AND Gates
The comparator can be used as three input AND gate. The
operation of the gate is as follow:
The resistor divider at the inverting input establishes a ref-
erence voltage at that node. The non-inverting input is the
sum of the voltages at the inputs divided by the voltage
dividers. The output will go high only when all three inputs
are high, casing the voltage at the non-inverting input to go
above that at inverting input. The circuit values shown work
for a ″0″ equal to ground and a ″1″ equal to 5V.
The resistor values can be altered if different logic levels are
desired. If more inputs are required, diodes are recom-
mended to improve the voltage margin when all but one of
the inputs are high.
DS100080-10
FIGURE 13. OR Gate
ORing the Output
By the inherit nature of an open collector comparator, the
outputs of several comparators can be tied together with a
pull up resistor to Vcc. If one or more of the comparators
outputs goes low, the output Vo will go low.

General Description
The LMV393 and LMV339 are low voltage (2.7-5V) versions of the dual and quad comparators, LM393/339,
which are specified at 5-30V. The LMV331 is the single version, which is available in space saving SC70-5
and SOT23-5 packages. SC70-5 is approximately half the size of SOT23-5.
The LMV393 is available in 8-pin SOIC and 8-pin MSOP. The LMV339 is available in 14-pin SOIC and 14-pin
TSSOP.
The LMV331/393/339 is the most cost-effective solution where space, low voltage, low power and price are
the primary specification in circuit design for portable consumer products. They offer specifications that meet
or exceed the familiar LM393/339 at a fraction of the supply current.
The chips are built with National's advanced Submicron Silicon-Gate BiCMOS process. The LMV331/393/339
have bipolar input and output stages for improved noise performance.
