LM139/LM239/LM339/LM2901/LM3302
Low Power Low Offset Voltage Quad Comparators
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 de-
signed 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 characteris-
tic 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 gen-
erators; 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 op-
erated from both plus and minus power supplies, they will di-
rectly interface with MOS logic — where the low power drain
of the LM339 is a distinct advantage over standard compara-
tors.
