ADG1402 Functional Block Diagram GENERAL DESCRIPTION The on resistance profile is very flat over the full analog input The ADG1401/ADG1402 contain a single-pole/single-throw range ensuring excellent linearity and low distortion when (SPST) switch. Figure 1 shows that with a logic input of 1, the switching audio signals. The iCMOS construction ensures switch of the ADG1401 is closed and that of the ADG1402 is ultralow power dissipation, making the part ideally suited for open. Each switch conducts equally well in both directions when portable and battery-powered instruments. on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.
