LMV761/LMV762
Low Voltage, Precision Comparator with Push-Pull
Output
General Description
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.
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.
The input offset voltage has a typical value of 200µV at room
temp and a 1mV limit over temp.
