(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(MAX) – TA)/ θJA . All numbers apply for packages soldered directly onto a PCB.

(1) Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device.
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlations using
statistical quality control (SQC) method.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and also depend on the application and configuration. The typical values are not tested and are not specified on shipped
production material.
(4) Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
(5) Positive current corresponds to current flowing into the device.

7 Detailed Description
7.1 Overview
The LPV7215 is a single-channel comparator with a push-pull output stage. This comparator is optimized for low-
power consumption and single-supply operation with greater than rail-to-rail input operation. The push-pull output
of the LPV7215 supports rail-to-rail output swing and interfaces with TTL/CMOS logic.

7.3 Feature Description
Low supply current and fast propagation delay distinguish the LPV7215 from other low-power comparators.
7.3.1 Input Stage
The LPV7215 has rail-to-rail input common-mode voltage range. It can operate at any differential input voltage
within this limit as long as the differential voltage is greater than zero. A differential input of zero volts may result
in oscillation.
The differential input stage of the comparator is a pair of PMOS and NMOS transistors, therefore, no current
flows into the device. The input bias current measured is the leakage current in the MOS transistors and input
protection diodes. This low bias current allows the comparator to interface with a variety of circuitry and devices
with minimal concern about matching the input resistances.
The input to the comparator is protected from excessive voltage by internal ESD diodes connected to both supply
rails. This protects the circuit from both ESD events, as well as signals that significantly exceed the supply
voltages. When this occurs the ESD protection diodes becomes forward-biased and draws current into these
structures, resulting in no input current to the terminals of the comparator. Until this occurs, there is essentially
no input current to the diodes. As a result, placing a large resistor in series with an input that may be exposed to
large voltages, limits the input current but have no other noticeable effect.

Feature Description (continued)
7.3.2 Output Stage
The LPV7215 has a MOS push-pull rail-to-rail output stage. The push-pull transistor configuration of the output
keeps the total system power consumption to a minimum. The only current consumed by the LPV7215 is the less
than 1-µA supply current and the current going directly into the load. No power is wasted through the pullup
resistor when the output is low. The output stage is specifically designed with dead time between the time when
one transistor is turned off and the other is turned on (break-before-make) to minimize shoot through currents.
The internal logic controls the break-before-make timing of the output transistors. The break-before-make delay
varies with temperature and power condition.
7.3.3 Output Current
Even though the LPV7215 uses less than 1-µA supply current, the outputs are able to drive very large currents.
The LPV7215 can source up to 17 mA and can sink up to 19 mA, when operated at 5-V supply. This large
current handling capability allows driving heavy loads directly.
7.3.4 Response Time
Depending upon the amount of overdrive, the propagation delay is typically 6 to 30 µs. The curves showing
propagation delay vs overdrive in the Typical Characteristics section shows the delay time when the input is
preset with 100 mV across the inputs and then is driven the other way by 10 mV to 500 mV.
The output signal can show a step during switching depending on the load. A fast RC time constant due to both
small capacitive and resistive loads shows a significant step in the output signal. A slow RC time constant due to
either a large resistive or capacitive load has a clipped corner on the output signal. The step is observed more
prominently during a falling transition from high to low.
The plot in Figure 29 shows the output for single 5-V supply with a 100-kΩ resistor. The step is at 1.3 V.

7.4 Device Functional Modes
7.4.1 Capacitive and Resistive Loads
The propagation delay is not affected by capacitive loads at the output of the LPV7215. However, resistive loads
slightly affect the propagation delay on the falling edge by a reduction of almost 2 µs depending on the load
resistance value.
7.4.2 Noise
Most comparators have rather low gain. This allows the output to spend time between high and low when the
input signal changes slowly. The result is that the output may oscillate between high and low when the
differential input is near zero. The exceptionally high gain of this comparator, 120 dB, eliminates this problem.
Less than 1 µV of change on the input drives the output from one rail to the other rail. If the input signal is noisy,
the output cannot ignore the noise unless some hysteresis is provided by positive feedback (see Hysteresis).
7.4.3 Hysteresis
To improve propagation delay when low overdrive is needed, hysteresis can be added.
7.4.4 Inverting Comparator With Hysteresis
The inverting comparator with hysteresis requires a three resistor network that is referenced to the supply voltage
V+ of the comparator as shown in Figure 31. When VIN at the inverting input is less than VA, the voltage at the
noninverting node of the comparator (VIN < VA), the output voltage is high (for simplicity assume VO switches as
high as V+). The three network resistors can be represented as R1//R3 in series with R2.
The lower input trip voltage VA1 is defined as Equation 1.
VA1 = VCCR2 / ((R1//R3) + R2)
(1)
When VIN is greater than VA, the output voltage is low or 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 Equation 2.
VA2 = VCC (R2//R3) / ((R1+ (R2//R3)
(2)
The total hysteresis provided by the network is defined as ΔVA = VA1 – VA2, as shown in Equation 3.

DVA =
R1R2 + R1R3 + R2R3

7.4.5 Noninverting Comparator With Hysteresis
A noninverting 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 Equation 4.

To make the comparator switch back to its low state, VIN must equal VREF before VA again equals VREF. VIN2 can

7.4.6 Zero Crossing Detector
In a zero crossing detector circuit, the inverting input is connected to ground and the noninverting input is
connected to a 100-mVPP AC signal. As the signal at the noninverting input crosses 0 V, the comparator’s output
changes state.
Figure 34. Zero Crossing Detector
To improve switching times and to center the input threshold to ground a small amount of positive feedback is
added to the circuit. The voltage divider, R4 and R5, establishes a reference voltage, V1, at the positive input. By
making the series resistance, R1 plus R2 equal to R5, the switching condition, V1 = V2, is satisfied when VIN = 0.
The positive feedback resistor, R6, is made very large with respect to R5 (R6 = 2000 R5). The resultant hysteresis
established by this network is very small (ΔV1 < 10 mV) but it is sufficient to insure rapid output voltage
transitions. Diode D1 is used to insure that the inverting input terminal of the comparator never goes below
approximately −100 mV. As the input terminal goes negative, D1 will forward bias, clamping the node between R1
and R2 to approximately −700 mV. This sets up a voltage divider with R2 and R3 preventing V2 from going below
ground. The maximum negative input overdrive is limited by the current handling ability of D1.

Instead of tying the inverting input to 0 V, the inverting input can be tied to a reference voltage. As the input on
the noninverting input passes the VREF threshold, the comparator’s output changes state. It is important to use a
stable reference voltage to ensure a consistent switching point.

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 LPV7215 is an ultra-low-power comparator with a typical power supply current of 580 nA. It has the best-in-
class power supply current versus propagation delay performance available among TI's low-power comparators.
The propagation delay is as low as 4.5 µs with 100-mV overdrive at 1.8-V supply.

8.2.1.1 Design Requirements
A typical application for a comparator is as a square wave oscillator. The circuit in Figure 38 generates a square
wave whose period is set by the RC time constant of the capacitor C1 and resistor R4. The maximum frequency
is limited by the large signal propagation delay of the comparator and by the capacitive loading at the output,
which limits the output slew rate.

Typical Applications (continued)
Consider the output of Figure 38 to be high to analyze the circuit. That implies that the inverted input (VC) is
lower than the noninverting input (VA). This causes the C1 to be charged through R4, and the voltage VC
increases until it is equal to the noninverting input. The value of VA at this point is in Equation 8.
V
CC ´R2
VA1 =
R2 + R1 P R3
(8)
If R1 = R2 = R3 then VA1 = 2 VCC/3
At this point the comparator switches pulling down the output to the negative rail. The value of VA at this point, as
shown in Equation 9:
VCC(R2 P R3)
=
R1 + (R2 P R3)
VA2
(9)
If R1 = R2 = R3 then VA2 = VCC/3
The capacitor C1 now discharges through R4, and the voltage VC decreases until it is equal to VA2, at which point
the comparator switches again, bringing it back to the initial stage. The time period is equal to twice the time it
takes to discharge C1 from 2 VCC/3 to VCC/3, which is given by R4C1 × ln2. Hence the formula for the frequency is
given by Equation 10:
F = 1/(2 × R4 × C1 × ln2)
(10)
8.2.1.3 Application Curves
Figure 39 shows the simulated results of an oscillator using the following values:
1. R1 = R2 = R3 = R4 = 100 kΩ
2. C1 = 100 pF, CL = 20 pF

8.2.2 Window Detector
A window detector monitors the input signal to determine if it falls between two voltage levels.
The comparator outputs A and B are high only when VREF1 < VIN < VREF2 or within the window. These are defined
as:
VREF1 = R3 / (R1+ R2 + R3) × V+
(11)
(12)
VREF2 = (R2+ R3) / (R1 + R2 + R3) × V+

Typical Applications (continued)
8.2.3 Crystal Oscillator
A simple crystal oscillator using the LPV7215 is shown in Figure 42. Resistors R1 and R2 set the bias point at the
comparator’s noninverting input. Resistors, R3 and R4 and capacitor C1 set 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.

8.2.4 IR Receiver
The LPV7215 can also 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 crosses the
voltage applied by the voltage divider to the inverting input, the output transitions.

9 Power Supply Recommendations
Comparators are very sensitive to input noise. To minimize supply noise, power supplies must be capacitively
decoupled by a 0.01-µF ceramic capacitor in parallel with a 10-µF electrolytic capacitor.
10 Layout
10.1 Layout Guidelines
Proper grounding and the use of a ground plane help ensure the specified performance of the LPV7215.
Minimizing trace lengths, reducing unwanted parasitic capacitance and using surface-mount components also
helps.
