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.
