Low Power Low Offset Voltage Quad Comparators
General DescriptionThe LM139 series consistsof four independent precision
voltage comparators withan offset voltage specificationas
lowas2 mV maxforall four comparators. These were
designed specificallyto operate froma single power supply
overa wide rangeof voltages. Operation from split power
suppliesis also possible and the low power supply current
drainis independentof the magnitudeof the power supply
voltage. These comparators also havea unique characteris-
ticin that the input common-mode voltage range includes
ground, even though operated froma single power supply
voltage.
Application areas include limit comparators, simple analogto
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
designedto directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, theywill
directly interface with MOS logic— where the low power
drainof the LM139/LM139Aisa distinct advantage over
standard comparators.
Features Wide supply voltage range LM139/139A Series 2to36 VDCor ±1to ±18 VDC Very low supply current drain (0.8 mA)— independent supply voltage Low input biasing current: 25nA Low input offset current: ±5nA Offset voltage: ±1mV Input common-mode voltage range includes GND Differential input voltage range equalto the power
supply voltage Low output saturation voltage: 250 mVat4 mA Output voltage compatible with TTL, DTL, ECL, MOS
and CMOS logic systems
Advantages High precision comparators Reduced VOS drift over temperature Eliminates needfor dual supplies Allows sensing near GND Compatible withall formsof logic Power drain suitablefor battery operation
