LM139/LM239/LM339/LM2901/LM3302

Low Power Low Offset Voltage Quad Comparators

n Reduced V_OSdrift over temperature

n Eliminates need for dual supplies

The LM139 series consists of four independent precision

n Allows sensing near GND

General Description

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

n Compatible with all forms of logic

n Power drain suitable for battery operation

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.

Features

n Wide supply voltage range

or 1 to 14 V_DC

n Very low supply current drain (0.8 mA) — independent

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.
