Supply voltage +/- 18 or 36 V, Low Power Quad Voltage Comparators These devices consist of four independent precision voltage comparators with an offset voltage specifications as low as 2 mV (Max.) All these comparators were designed specifically to operate from a single power supply aver a wide range of voltages. Operation from split power supplies is also possible. 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.
