Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is  
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test condition, see the Electrical Characteristics.  
Note 2: Unless otherwise specified human body model is 1.5kΩ in series with 100pF. Machine model 200pF.  
Note 3: 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 such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ >  
TA. See Application section for information on temperature de-rating of this device. Absolute Maximum Rating indicate junction temperature limits beyond which  
the device may be permanently degraded, either mechanically or electrically.  
Note 4: The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is  
PD = (TJ(MAX)-TA)θJA. All numbers apply for packages soldered directly into a PC board.  
Note 5: Maximum temperature guarantee range is −40°C to 125°C.  
Note 6: Typical values represent the most likely parametric norm.  
Note 7: All limits are guaranteed by testing or statistical analysis.  
Note 8: Guaranteed by design  
Note 9: Applies to both single supply and split supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the  
maximum allowed junction temperature of 150°C. Output current in excess of ±25 mA over long term may adversely affect reliability.

Application Information  
BASIC COMPARATOR  
A basic comparator circuit is used to convert analog input  
signals to digital output signals. The comparator compares an  
input voltage (VIN) at the non-inverting input to the reference  
voltage (VREF) at the inverting pin. If VIN is less than VREF the  
output (VO) is low (VOL). However, if VIN is greater than  
VREF, the output voltage (VO) is high (VOH).  
20037026  
20037028  
20037027  
FIGURE 2. Non-Inverting Comparator Configuration  
INPUT  
20037031  
The LMV761/LMV762 have near zero input bias current. This  
allows very high resistance circuits to be used without any  
concern for matching input resistances. This also allows the  
use of very small capacitors in R-C type timing circuits. This  
reduces the cost of the capacitors and amount of board space  
used.  
FIGURE 1. Basic Comparator  
HYSTERESIS  
The basic comparator configuration may oscillate or produce  
a noisy output if the applied differential input is near the  
comparator's input offset voltage. This tends to occur when  
the voltage on one input is equal or very close to the other  
input voltage. Adding hysteresis can prevent this problem.  
Hysteresis creates two switching thresholds (one for the rising  
input voltage and the other for the falling input voltage). Hys-  
teresis is the voltage difference between the two switching  
thresholds. When both inputs are nearly equal, hysteresis  
causes one input to effectively move quickly past the other.  
Thus, moving the input out of the region in which oscillation  
may occur.  
SHUTDOWN MODE  
The LMV761 features a low-power shutdown pin that is acti-  
vated by driving SD low. In shutdown mode, the output is in  
a high impedance state, supply current is reduced to 20nA  
and the comparator is disabled. Driving SD high will turn the  
comparator on. The SD pin should not be left unconnected  
due to the fact that it is a high impedance input. When left  
unconnected, the output will be at an unknown voltage. Also  
do not three-state the SD pin.  
The maximum input voltage for SD is 5.5V, referred to ground  
and is not limited by VCC. This allows the use of 5V logic to  
drive SD while VCC operates at a lower voltage, such as 3V.  
Hysteresis can easily be added to a comparator in a non-in-  
verting configuration with two resistors and positive feedback  
Figure 2. The output will switch from low to high when VIN rises  
up to VIN1, where VIN1 is calculated by  
The logic threshold limits for SD are proportional to VCC  
.
BOARD LAYOUT AND BYPASSING  
VIN1 = (VREF(R1+R2))/R2  
The LMV761/LMV762 is designed to be stable and oscillation  
free, but it is still important to include the proper bypass ca-  
pacitors and ground pickups. Ceramic 0.1μF capacitors  
should be placed at both supplies to provide clean switching.  
Minimize the length of signal traces to reduce stray capaci-  
tance.  
The output will switch from high to low when VIN falls to VIN2  
where VIN2 is calculated by  
,
VIN2 = (VREF(R1+R2) – VCC R1)/R2  
The Hysteresis is the difference between VIN1 and VIN2  
.
ΔVIN = VIN1 - VIN2  
= ((VREF(R1+R2))/R2)-((VREF(R1+R2)) - (VCC R1))/R2)  
= VCC R1/R2
