Quad voltage comparator

DESCRIPTION

PIN CONFIGURATION

The LM139 series consists of four independent precision voltage

comparators, with an offset voltage specification as low as 2.0mV

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 LM139 series was designed to directly interface with TTL and

CMOS. When operated from both plus and minus power supplies,

the LM139 series will directly interface with MOS logic where their

low power drain is a distinct advantage over standard comparators.
