m Voltage parators LM13.A/LM239A/LM33,A low offset voltage quad parators general description The LM1~9A series consists of four independent precision voltage parators with an offset voltage specification of 2 mV. max. for all four parators 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 draiA is independent of the magnitude of the power supply voltage. These parators also have a unique characteristic in that the input mon- mode voltage range includes ground, even though operated from a single power supply voltage. Application areas...
