7 Detailed Description
7.1 Overview
LMV7219 is a single supply comparator with internal hysteresis, 7 ns of propagation delay and only 1.1 mA of
supply current.
The LMV7219 has a typical input common mode voltage range of 0.2 V below the ground to 1 V below Vcc. The
differential input stage is a pair of PNP transistors, therefore, the input bias current flows out of the device. 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.
7.2 Functional Block Diagram
7.3 Feature Description
If one of the inputs 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.
7.4 Device Functional Modes
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 damages to the input stage.
The LMV7219 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 1.1 mA at 5 V, thus conserving power consumption.
Most high-speed comparators oscillate when the voltage of one of the inputs is close to or equal to the voltage
on the other input due to noise or undesirable feedback. The LMV7219 has 7 mV of internal hysteresis to counter
parasitic effects and noise. The hysteresis does not change significantly with the supply voltages and the
common mode input voltages as reflected in the specification table.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The following section explains in detail how to manipulate the hysteresis voltage of the LMV7219. Detailed
expressions are provided along with practical considerations for designing hysteresis.
8.2 Typical Application
Figure 14 shows the typical method of adding external hysteresis to a comparator. The positive feedback is
responsible for shifting the comparator trip point depending on the state of the output.
Figure 14. Additional Hysteresis
8.2.1 Design Requirements
The internal hysteresis creates two trip points, one for the rising input voltage and one for the falling input
voltage, as shown in Figure 19. The difference between the trip points is the hysteresis. With internal hysteresis,
when the comparator's input voltages are equal, the hysteresis effectively causes one comparator-input voltage
to move quickly past the other, thus taking the input out of the region where oscillation occurs. Standard
comparators require hysteresis to be added with external resistors. The fixed internal hysteresis eliminates these
resistors.
8.2.2 Detailed Design Procedure
8.2.2.1 Additional Hysteresis
If additional hysteresis is desired, this can be done with the addition of three resistors using positive feedback, as
shown in Figure 14. The positive feedback method slows the comparator response time. Calculate the resistor
values as follows:
1. Select R3. The current through R3 should be greater than the input bias current to minimize errors. The
current through R3 (IF) at the trip point is (VREF - VOUT) /R3. Consider the two possible output states when solving
for R3, and use the smaller of the two resulting resistor values. The two formulas are:
R3 = VREF/IF(1)
When VOUT = 0:

Submit Documentation FeedbackCopyright © 2000–2016, Texas Instruments Incorporated
Typical Application (continued)
R3 = VCC - VREF /IF(2)
When VOUT = VCC:
2. Choose a hysteresis band required (VHB).
3. Calculate R1, where R1 = R3 X(VHB/VCC)
4. Choose the trip point for VIN rising. This is the threshold voltage (VTHR) at which the comparator switches from
low to high as VIN rises about the trip point.
5. Calculate R2 as follows:
(3)
6. Verify the trip voltage and hysteresis as follows:
(4)
This method is recommended for additional hysteresis of up to a few hundred millivolts. Beyond that, the
impedance of R3 is low enough to affect the bias string and adjustment of R1 may be also required.
8.2.2.2 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 0 V, the comparator's output Changes State.
Figure 15. Zero-Crossing Detector
8.2.2.3 Threshold Detector
Instead of tying the inverting input to 0 V, 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.

Figure 16. Threshold Detector
8.2.2.4 Crystal Oscillator
A simple crystal oscillator using the LMV7219 is shown in Figure 17. 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 17. Crystal Oscillator
8.2.2.5 IR Receiver
The LMV7219 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.

should be decoupled with low inductance, often ceramic, capacitors to ground less than 0.5 inches from the
device pins. The use of ground plane is recommended, and as in most high speed devices, it is advisable to
remove ground plane close to device sensitive pins such as the inputs.
10 Layout
10.1 Layout Guidelines
10.1.1 Circuit Layout and Bypassing
The LMV7219 requires high-speed layout. Follow these layout guidelines:
1. Power supply bypassing is critical, and will improve stability and eliminate possible output chatter. A
decoupling capacitor such as 0.1-µF ceramic should be placed as close as possible to V+pin (and to V- pin if
used with dual supplies) as shown in Figure 20. An additional 2.2-µF tantalum capacitor may be required for
extra noise reduction.
2. Keep all leads short to reduce stray capacitance and lead inductance. It will also minimize unwanted parasitic
feedback around the comparator.
3. The device should be soldered directly to the PC board instead of using a socket.
4. Use a PC board with a good, unbroken low inductance ground plane as shown in Figure 20. Make sure
ground paths are low-impedance, especially were heavier currents are flowing.
5. Input traces should be kept away from output traces. This can be achieved by running a topside ground
plane between the output and inputs.
6. Run the ground trace under the device up to the bypass capacitor to shield the inputs from the outputs.
7. To prevent parasitic feedback when input signals are slow-moving, a small capacitor of 1000 pF or less can
be placed between the inputs. It can also help eliminate oscillations in the transition region. However, this
capacitor can cause some degradation to tpd when the source impedance is low.
