low power low offset voltage quad comparators lm339 description outline drawing the lm 339 consists of four independent precision voltage comparators.these were designed specifically to operate from a signal power supply over a wide range of voltage.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.the lm339 also have a unique characteristic in that the input common-mode voltage range includes ground,even though operated from a single power supply voltage. fea t ure low input biasing current 25na typ . . d i p 1 4 low input of fset current 5.0na typ . . low output saturation voltage 130m v . output voltage com p atible with ttl,cmos. sop14 p i n c o n f i g u r a t i o n b l o c k d i a g r a m tiger electronic co.,ltd
