Working Principles

The ADG426BN operates based on the principle of field-effect transistors (FETs). When a control voltage is applied to the corresponding input pin, the FET switches on, connecting the input signal to the output pin. Conversely, when the control voltage is removed, the FET switches off, isolating the input from the output.
