philips semiconductors product specification lm193/a/293/a/393/a/2903 low power dual voltage comparator 1 1995 nov 27 853-0932 16050 description the lm193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0mv max. for two comparators which 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. the lm193 series was designed to 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 drain is a distinct advantage over standard comparators. features ? wide single supply voltage range 2.0vdc to 36vdc or dual supplies 1.0vdc, to 18vdc ? v ery low supply current drain (0.8ma) independent of supply voltage (2.0mw/comparator at 5.0vdc) ? low input biasing current 25na ? low input offset current 5na and offset voltage 2mv ? input common-mode voltage range includes ground ? dif ferential input voltage range equal to the power supply voltage ? low output 250mv at 4ma saturation voltage ? output voltage compatible with ttl, dtl, ecl, mos and cmos logic systems applications ? a/d converters ? wide range vco ? mos clock generator ? high voltage logic gate ? multivibrators pin configuration 1 2 3 4 5 6 7 8 d, n, fe packages a b top view output a inverting input a noninverting input a gnd v+ output b inverting input b noninverting input b sl00079 figure 1. pin configuration equivalent circuit v + 100 m a 3.5 m a 3.5 m a 100 m a q1 q2 q3 q4 q8 q7 q6 q5 input output + input (one comparator only) sl00080 figure 2. equivalent circuit ordering information description temperature range order code dwg # 8-pin ceramic dual in-line package (cerdip) -55 c to +125 c lm193fe 0580a 8-pin ceramic dual in-line package (cerdip) -25 c to +85 c lm293fe 0580a 8-pin plastic dual in-line package (dip) -25 c to +85 c lm293n sot97-1 8-pin plastic small outline (so) package -25 c to +85 c lm293d sot96-1 8-pin plastic dual in-line package (dip) -25 c to +85 c lm293an sot97-1 8-pin ceramic dual in-line package (cerdip) 0 to +70 c lm393afe 0580a 8-pin ceramic dual in-line package (cerdip) 0 to +70 c lm393fe 0580a 8-pin plastic small outline (so) package 0 to +70 c lm393d sot96-1 8-pin plastic dual in-line package (dip) 0 to +70 c lm393n sot97-1 8-pin plastic dual in-line package (dip) 0 to +70 c lm393an sot97-1 8-pin plastic dual in-line package (dip) -40 c to +125 c lm2903n sot97-1 8-pin plastic dual in-line package (dip) -40 c to +125 c lm2903d sot97-1
