low power low offset voltage quad comparators lm2901 description outline drawing the lm2901 consists of four independent precision voltage com p arators.these were designed specifically to operate from a signal pow er supply over a w i de range of voltage.operation from split power supplies is also possible and the low pow er supply current drain is independent of the m a gnitude of the pow er supply voltage.the lm2901 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
