Working Principles

The DG301ACJ+ operates based on the principle of field-effect transistors (FETs). It utilizes MOSFET technology to create a conductive channel between the NO (Normally Open) and COM (Common) pins when the control signal at the EN (Enable) pin is active. This allows the analog signal to pass through the switch, while in the inactive state, the switch remains open, preventing the signal from passing through.
