Working Principles

The DG418DJ+ operates based on the principle of field-effect transistors (FETs). It utilizes MOSFET technology to control the flow of signals by adjusting the gate voltage. When the input control signal is applied, the corresponding channel is activated, allowing the signal to pass through to the output. Conversely, when the input control signal is absent or at a low voltage, the channel remains closed, preventing signal transmission.
