LMV761/LMV762  
Low Voltage, Precision Comparator with Push-Pull  
Output  
General Description  
Features  
The LMV761/762 are precision comparators intended for  
applications requiring low noise and low input offset voltage.  
The LV761 single has a shutdown pin that can be used to  
disable the device and reduce the supply current. The  
LMV761 is available in a space saving SOT23-6 or SOIC−8  
package. The LMV762 dual is available in SOIC−8 or  
MSOP-8 package.  
(VS = 5V, TA = 25˚C, Typical values unless specified)

They feature a CMOS input and Push-Pull output stage. The  
Push-Pull output stage eliminates the need for an external  
pull-up resistor.  
The LMV761/762 are designed to meet the demands of  
small size, low power and high performance required by  
portable and battery operated electronics.  
n Ideal for 2.7V and 5V single supply applications  
n Available in space-saving packages:  
6-Pin SOT23 (single w/shutdown)  
The input offset voltage has a typical value of 200µV at room  
temp and a 1mV limit over temp.  
8-Pin SOIC (single w/shutdown)  
8-Pin SOIC/MSOP (dual without shutdown)  
Applications  
n Portable and battery-powered systems  
n Scanners  
n Set top boxes  
n High speed differential line receiver  
n Window comparators  
n Zero-crossing detectors  
n High speed sampling circuits
