About Interface - Analog Switches, Multiplexers, Demultiplexers
Analog switches, multiplexers, and demultiplexers are interface components used to route analog signals between multiple input and output channels. Analog switches allow or block the passage of analog signals based on control signals, while multiplexers select one of several input signals for transmission to a common output. Demultiplexers perform the opposite function, routing a single input signal to one of several output channels. These interface components are widely used in test and measurement equipment, data acquisition systems, audio/video routers, and instrumentation applications.
