Inspire the Linear Power
Low Power Low Offset Voltage Dual
Comparators
Description
The LM393 consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0
mV max for two comparators which were designed specifically
to operate from a single power supply over a wide range of
voltages. 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. These comparators
also have a unique characteristic in that the input commonmode voltage range includes ground, even though operated
from a single power supply voltage.
Application areas include limit comparators, simple analog to
digital converters; pulse, squarewave and time delay
generators; wide range VCO; MOS clock timers;
multivibrators and high voltage digital logic gates. The LM393
was designed to directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, the LM393
will directly interface with MOS logic where their low power
drain is a distinct advantage over standard comparators.
