Working Principles

The DG408DY-T1 is an analog multiplexer/demultiplexer IC that operates by selectively connecting one of the eight input channels to the output channel. It uses a combination of MOSFET switches and control logic to achieve this functionality. The on-resistance of the switches is kept low to minimize signal distortion. The break-before-make feature ensures that there is no short-circuit during channel switching.
