LM393N/D
Dual Differential Comparators
DESCRIPTION：
Outline Drawing
The
LM393
consists of two independent voltage
comparators with an offset voltage specification as low as
2.0mV max.for two comparators which were designed
specifically to operation from a single power supply over a
wide range of voltages. Operate from split power supplies is
also possible,and the low power supply current drain is
independent of the magnitude of the power supply
voltage.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.
