Overview
The LMV761MF is a precision comparator manufactured by Texas Instruments. It is part of the LMV76x series, designed to meet the demands of small size, low power, and high performance, particularly in portable and battery-operated electronics. The LMV761MF features a CMOS input and a push-pull output stage, eliminating the need for an external pullup resistor. It is available in space-saving packages, including a 6-pin SOT-23 and an 8-pin SOIC, both with a shutdown pin to disable the device and reduce supply current.
