Working Principles

The ADG202ATQ is based on CMOS technology, which allows for low power consumption and high precision switching. When a control voltage is applied to the corresponding switch control pin (S1-S4), the internal switch connects the input signal (D1-D4) to the output terminal. The on-resistance of the switch is minimized to ensure minimal signal distortion.
