Working Principles

The DG408DVZ is an analog multiplexer/demultiplexer IC that routes analog signals between multiple input/output channels. It operates based on the principle of MOSFET switches, where the control signals determine which channel is connected to the common terminal. When a specific channel is selected, the corresponding MOSFET switch turns on, allowing the analog signal to pass through. The low on-resistance and off-leakage current ensure minimal signal distortion and power consumption.
