LM2901N/D
Low Power Low Offset Voltage Quad Comparators
DESCRIPTION：
The
LM2901
consists of four independent precision
voltage comparators.These were designed specifically to
operate from a signal power supply over a wide range of
voltage.Operation from split power supplies is also possible
and the low power supply current drain is independent of the
magnitude of the power supply voltage.The
LM2901
also have
a unique characteristic in that the input common-mode voltage
range includes ground,even though operated from a single
power supply voltage.
