DESCRIPTION
The LM339 consists of four independent precision voltage comparators, with an offset voltage
specification as low as 20㎷ max for each comparator, 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 they are operated from a single power supply voltage.
The LM339 series was designed to directly interface with TTL and CMOS.
When operated from both plus and minus power supplies, the LM339 series will directly interface with
MOS logic where their low power drain is a distinct advantage over standard comparators.
