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.
