To best meet customer application objectives, Analog Devices offers a broad array of switches and multiplexers that includes single to multiple switch elements with a variety of signal ranges in a variety of packages. Medical, consumer, communications, automotive, industrial, and instrumentation systems are just a few of the systems that use ADI switches and multiplexers. Analog Switches, Multiplexers, and Demultiplexers are used for the route alteration of the data it carries.
Differences Between Switch, Multiplexer, and Demultiplexer:
Switch
An analog switch can deliver one of two signals to a headphone amplifier, or it can turn on or off an audio signal in response to a MUTE command. CMOS technology integrated circuits are most frequently used for implementation.
Types of Switches:
Various switches are used in electronic devices for specific purposes, that includes,
- ONE-WAY (SINGLE-POLE) ELECTRICAL SWITCH.
- TWO-WAY (DOUBLE-POLE) ELECTRICAL SWITCH.
- DO NOT DISTURB THE SWITCH.
- LIGHT DIMMER / STEPLESS REGULATOR.
- BELL PUSH SWITCH
Common Applications of Switches:
- Interface isolation and protection
- Telecommunication routing
- Audio and videos signals (A/VS)
- The transfer of audio and video (A/VS) data
Multiplexer
Instead of having a device for each input signal, a multiplexer enables several input signals to share a single device or resource, such as an analog-to-digital converter or the transmission of a communication medium. Boolean functions with numerous variables can also be implemented using multiplexers.
Commonly Used Types of Multiplexer:
There are three major types of Multiplexers, which are given below.
- Multi-frequency frequency division (FDM)
- Multiplexing by time division (TDM)
- WDM stands for Wavelength Division Multiplexing.
Significant Uses of Multiplexers:
Multiplexers are primarily used in the following ways:
- Data transmission techniques
- Transmission from a Satellite's Computer System
- Telephonic systems
- The memory of the computer systems
Demultiplexer
One to many is what a demultiplexer signifies. A circuit with one input and numerous outputs is known as a demultiplexer. Any input can be directed toward the output by using a control signal. One to two, one to four, one to eight, and one to sixteen demultiplexers are a few examples of demultiplexers.
Major Applications of Demultiplexers:
- Demultiplexers are mainly used in the following systems:
- Series to Parallel Converter
- Data communication systems
- Arithmetic and logical unit (ALU) of electronic devices
