Low Power Low Offset Voltage Dual Comparators
General DescriptionThe LM193 series consistsof two independent precision
voltage comparators withan offset voltage specificationas
lowas 2.0 mV maxfor two comparators which were de-
signed 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 LM193 series was
designedto directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, the
LM193 series will directly interface with MOS logic where
their low power drainisa distinct advantage over standard
comparators.
The LM393 and LM2903 parts are availablein National’s
innovative thin micro SMD package with8 (12 mil) large
bumps.
Advantages High precision comparators Reduced VOS drift over temperature Eliminates needfor dual supplies Allows sensing near ground Compatible withall formsof logic Power drain suitablefor battery operation
Features Wide supply Voltage range: 2.0Vto 36V Singleor dual supplies: ±1.0Vto ±18V Very low supply current drain (0.4 mA)— independent supply voltage Low input biasing current: 25nA Low input offset current: ±5nA Maximum offset voltage: ±3mV Input common-mode voltage range includes ground 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 Availablein the 8-Bump (12 mil) micro SMD package See AN-1112for micro SMD considerations
