BIPOLAR ANALOG INTEGRATED CIRCUIT
µ
PC393
LOW POWER DUAL COMPARATORS
DESCRIPTION
The
µ
PC393 is a dual comparator which is designed
to operate from a single power supply over a wide range
of voltage. Operation from split power supplies is also
possible and the power supply current drain is very low.
Further advantage, the input common-mode voltage in-
cludes ground, even though operated from a single power
supply voltage.
FEATURES
• Common-mode input voltage range includes V
–
• Wide supply voltage range
