The ADG1613BCPZ-REEL contains four independent single-pole/single-throw (SPST) switches. The ADG1613BCPZ-REEL has two switches with digital control logic similar to that of the ADG1611; the logic is inverted on the other two switches. Each switch conducts equally well in both 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.
