The LM1~9A series consists of four independent precision voltage parators with an offset voltage specification of 2 mV. 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.
