General Description
The LM139 series consists of four independent precision
voltage comparators with an offset voltage specification as
low as 2 mV max for all four comparators. These 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.
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 LM139 series was
designed to directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, they will
directly interface with MOS logicÐ where the low power
drain of the LM339 is a distinct advantage over standard
comparators.
