Operation from split power n Compatible with all forms of logic supplies is also possible and the low power supply current n Power drain suitable for battery operation drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteris- tic in that the input common-mode voltage range includes Features ground, even though operated from a single power supply n Wide supply voltage. -- Voltage range: 2.0V to 36V Application areas include limit comparators, simple analog to -- Single or dual supplies:
