Overview
The LMV7275MG is a low-power comparator from Texas Instruments, designed for applications requiring low voltage, low power consumption, and minimal space. This device is part of the LMV727x family, which includes single and dual comparators characterized at supply voltages of 1.8 V, 2.7 V, and 5 V. The LMV7275MG is available in SC70 and SOT-23 packages, making it ideal for space-critical designs. It features an open-drain output stage, which allows for wired-OR configurations and level-shifting applications up to 5.5 V, regardless of the supply voltage.
