ADG419 can be operated from a single rail power supply. The part is fully specified with a single 12 V power supply Each switch of the ADG419 conducts equally well in both and remains functional with single supplies as low as 5 V. directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The ADG419 exhibits break-before-make switching action. Rev.
