APPLICATION INFORMATION
The LMV7235/LMV7239/LMV7239Q are single supply comparators with 75ns of propagation delay and only
65µA of supply current.
The LMV7235/LMV7239/LMV7239Q are rail-to-rail input and output. The typical input common mode voltage
range of −0.2V below the ground to 0.2V above the supply. The LMV7235/LMV7239/LMV7239Q use a
complimentary PNP and NPN input stage in which the PNP stage senses common mode voltage near V−and the
NPN stage senses common mode voltage near V+. If either of the input signals falls below the negative common
mode limit, the parasitic PN junction formed by the substrate and the base of the PNP will turn on resulting in an
increase of input bias current.
If one of the input goes above the positive common mode limit, the output will still maintain the correct logic level
as long as the other input stays within the common mode range. However, the propagation delay will increase.
When both inputs are outside the common mode voltage range, current saturation occurs in the input stage, and
the output becomes unpredictable.
The propagation delay does not increase significantly with large differential input voltages. However, large
differential voltages greater than the supply voltage should be avoided to prevent damage to the input stage.
The LMV7239 has a push-pull output. When the output switches, there is a direct path between VCC and ground,
causing high output sinking or sourcing current during the transition. After the transition, the output current
decreases and the supply current settles back to about 65µA at 5V, thus conserving power consumption.
The LMV7235 has an open drain that 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.
CIRCUIT LAYOUT AND BYPASSING
The LMV7235/LMV7239/LMV7239Q require high speed layout. Follow these layout guidelines:
1. Use printed circuit board with a good, unbroken low-inductance ground plane.
2. Place a decoupling capacitor (0.1µF ceramic surface mount capacitor) as close as possible to VCC pin.
3. On the inputs and the output, keep lead lengths as short as possible to avoid unwanted parasitic feedback
around the comparator. Keep inputs away from output.
4. Solder the device directly to the printed circuit board rather than using a socket.
5. For slow moving input signals, take care to prevent parasitic feedback. A small capacitor (1000pF or less)
placed between the inputs can help eliminate oscillations in the transition region. This capacitor causes some
degradation to tPD when the source impedance is low.
6. The topside ground plane runs between the output and inputs.
7. Ground trace from the ground pin runs under the device up to the bypass capacitor, shielding the inputs from
the outputs.
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 comparator'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 is referenced to the supply voltage
VCC of the comparator, as shown in Figure 18. When VIN at the inverting input is less than VA, the voltage at the
non-inverting node of the comparator (VIN < VA), the output voltage is high (for simplicity assume VOswitches 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:
VA1 = VCCR2 / [(R1||R3) + R2] (1)

LMV7235, LMV7239
SNOS532M –SEPTEMBER 2000–REVISED FEBRUARY 2013
www.ti.com
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:
VA2 = VCC (R2||R3) / [(R1)+ (R2||R3)] (2)
The total hysteresis provided by the network is defined as:
Delta VA= VA1- VA2 (3)
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 follows:
RPULL-UP << RLOAD (4)
Figure 18. Inverting Comparator with Hysteresis
NON-INVERTING COMPARATOR WITH HYSTERESIS
A non inverting comparator with hysteresis requires a two resistor network, and a voltage reference (VREF) at the
inverting 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:
VIN1 = R1*(VREF / R2) + VREF (5)
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 VAwill again equal VREF. VIN can be calculated by:
VIN2 = [VREF (R1+ R2) - VCC R1] / R2 (6)
The hysteresis of this circuit is the difference between VIN1 and VIN2.
Delta VIN = VCC R1 / R2 (7)

ZERO-CROSSING DETECTOR
The inverting input is connected to ground and the non-inverting input is connected to 100mVp-p signal. As the
signal at the non-inverting input crosses 0V, the comparator's output changes state.

THRESHOLD DETECTOR
Instead of tying the inverting input to 0V, the inverting input can be tied to a reference voltage. The non-inverting
input is connected to the input. As the input passes the VREF threshold, the comparator's output changes state.

CRYSTAL OSCILLATOR
A simple crystal oscillator using the LMV7239 is shown below. Resistors R1 and R2 set the bias point at the
comparator's non-inverting input. Resistors R3, R4 and C1 sets the inverting input node at an appropriate DC
average level based on the output. The crystal's path provides resonant positive feedback and stable oscillation
occurs. The output duty cycle for this circuit is roughly 50%, but it is affected by resistor tolerances and to a
lesser extent by the comparator offset.
Figure 22. Crystal Oscillator
IR RECEIVER
The LMV7239 is an ideal candidate to be used as an infrared receiver. The infrared photo diode creates a
current relative to the amount of infrared light present. The current creates a voltage across RD. When this
voltage level cross the voltage applied by the voltage divider to the inverting input, the output transitions.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
