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.
