The LM393 series consists of two independent precision voltage comparators with an offset voltage
specification as low as 2.0㎷ 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 common-mode voltage range
includes ground, even though operated from a single power supply voltage.
The LM393 series was designed to directly interface with TTL and CMOS. When operated from both
plus and minus power supplies, the LM393 series will directly interface with MOS logic where their
low power drain is a distinct advantage over standard comparators.
