BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC393
LOW POWER DUAL COMPARATORS
DESCRIPTION
FEATURES
The µPC393 is a dual comparator which is designed
to operate from a single power supply over a wide range
• Common-mode input voltage range includes V–
• Wide supply voltage range
of voltage. Operation from split power supplies is also
2 V to 32 V (Single)
possible and the power supply current drain is very low.
±1 V to ±16 V (Split)
Further advantage, the input common-mode voltage in-
• Low supply current
cludes ground, even though operated from a single power
• Open collector output
supply voltage.
