philips semiconductors product data lm193a/293/a/393/a/2903 low power dual voltage comparator 2 2002 jul 12 853-0932 28616 description the lm193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mv 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 2.0 v dc to 32 v dc , or dual supplies 1.0 v dc , to 16 v dc ? very low supply current drain (0.8 ma) independent of supply voltage (2.0 mw/comparator at 5.0 v dc ) ? low input biasing current 25 na ? low input offset current 5 na and offset voltage 2 mv ? input common-mode voltage range includes ground ? differential input voltage range equal to the power supply voltage ? low output 250 mv at 4 ma 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 45 6 7 8 d, dp, and n packages ab top view output a inverting input a non-inverting input a gnd v+ output b inverting input b non-inverting 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 plastic dual in-line package (dip) 55 c to +125 c LM193AN 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 lm293n sot97-1 8-pin plastic small outline (so) package 25 c to +85 c lm293ad sot96-1 8-pin plastic dual in-line package (dip) 25 c to +85 c lm293an sot97-1 8-pin plastic small outline (so) package 0 c to +70 c lm393d sot96-1 8-pin plastic thin shrink small outline package (tssop) 0 c to +70 c lm393dp sot505-1 8-pin plastic dual in-line package (dip) 0 c to +70 c lm393n sot97-1 8-pin plastic small outline (so) package 0 c to +70 c lm393ad sot96-1 8-pin plastic dual in-line package (dip) 0 c to +70 c lm393an sot97-1 8-pin plastic small outline (so) package 40 c to +125 c lm2903d sot96-1 8-pin plastic dual in-line package (dip) 40 c to +125 c lm2903n sot97-1 8-pin plastic thin shrink small outline package (tssop) 40 c to +125 c lm2903dp sot505-1
