lm393介绍：

description
these devices consist of two independent low
voltage comparators designed specifically to
operate from a single supply over a wide range of
voltages. operation from split power supplies is
also possible.
these comparators also have a unique
characteristic in that the input common-mode
voltage range includes ground even though
operated from a single power supply voltage.
