Support is limited to customers who have already adopted these products. The μ PC393MF-DAA is dual comparator which is designed to operate for a single power supply. It includes features of low-voltage operation, a common-mode input voltage that range from V−(GND) level, an open collector output, and low current consumption. Furthermore, this product can operate on a split power supply and be used for an extensive comparison of various voltages. This package becomes smaller than μ PC393G2 package in existence because the package adopts the narrow body SOP that is generally used abroad.
