An analogue multiplexer uses analogue switches to choose one signal from numerous analogue inputs and route it to a single output line. Because analogue switches can transport signals bidirectionally, the analogue multiplexer may also be employed as a demultiplexer.
Designers are frequently confronted with determining the best cost-effective, power-efficient, and space-efficient method of digitizing many sensors or routing several transceivers onto a shared communications bus. To avoid duplicating whole signal chains and their relevant components, the approach is to share common resources.
This is performed by employing analogue multiplexers to multiplex the inputs. These may connect to the input of an analog-to-digital converter (ADC) and digitize each transducer in turn.
A multiplexer is a type of electrical switch that links several input sources to a single output line.Multiplexers are programmed to choose any of 2N inputs from a range of frequently available variants. The number of digital control lines equals N for each multiplexer 2N arrangement. As a result, a multiplexer requires three control lines.
The number of inputs or poles and the number of outputs or throws are used to characterize switch setups. A single-pole single-throw (SPST) switch has only one input and one output. SPDT switches have one input and two outputs.
Manufacturers of integrated circuits (ICs) frequently bundle numerous switches onto a single IC package and refer to the many switches as having multiple channels, such as the four-channel SPST switch.

For any multiplexer 2N configuration, the number of digital control lines equals N. As a result, three control lines are required for a multiplexer. Switch configurations are defined by the number of inputs or poles and the number of outputs or throws.

The Global Analog Switch Multiplexers Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The analogue switch IC portfolio of STMicroelectronics includes SPDT switches as well as bigger octal SPDT or quad DPDT switches. It has low on-resistances, 15 kV safety diodes, a negative charge pump, and a bandwidth that meets audio or USB requirements.
They come in small packaging, making them ideal for portable applications, but they can also handle any application that requires high-performance switching.Switches are used in portable applications to route a wide range of signals, such as audio to the speaker or headphones, or other signals from and towards sensors:Ensure a simple yet effective system implementation and high-speed signal compatibility for USB 2.0 applications
Switches are frequently used to multiplex or de-multiplex a wide range of signals. Switches, for example, are employed in portable applications to transport signals such as audio to a speaker or headphones.
With the growth of sensors and interfaces in new applications such as wearables, switches have also become the right option for routing signals from / towards each other, ensuring a simple and efficient system implementation.
Low RDS(on) analogue switches, such as the AS11P2TLR and AS21P2TLR, are ideal for low current/low voltage signals. It is designed to function in silicon gate C2MOS technology and has a very low ON resistance.
They can readily support high bandwidth, implement break-before-make delay time, and consume very little power. All inputs and outputs have safety circuits against
