Interface - Analog Switches, Multiplexers, Demultiplexers

Analog switches, multiplexers, and demultiplexers are electronic devices used to control multiple channels of analog signal or multiplex their analog signals. A variety of applications need these kinds of devices because they can control or control the number of inputs and outputs.

Analog Switches

Analog switches are the simplest form of interface between the different channels of analog signal. A single-pole switch device is capable of making or breaking the connection between two terminals; while a double-pole switch can make or break two separate connections between two pairs of ports. These switches are also used to control or route a single channel of analog signal between two ports.

Multiplexers and Demultiplexers

Multiplexers are devices that are capable of multiplexing multiple channels of analog signal into a single connection. These devices are commonly used to control the flow of a signal from one port to another depending upon the control signal applied to it. Demultiplexers are the opposite of multiplexers; they are used to direct the flow of analog signal from a single input port to multiple output ports.

PS301CPA

The PS301CPA is a fully integrated analog signal conditioning device used for signal acquisition and control within an industrial or process monitoring system. This device features an array of analog switches, multiplexers, and demultiplexers, as well as circuitry for differentiating the input signal and gain adjustment. The PS301CPA is designed to provide an optimized signal with the highest signal-to-noise ratio, to ensure accurate evaluation. It features two different types of analog switches: one type with two input ports, two output ports, and a common return port, and one type with two input ports, one output port, and one return port.The PS301CPA can also be programmed to a wide range of frequency settings. This allows it to be used for high and low frequency switching applications, from 1 kHz to 18 MHz, depending on the particular application.

Working Principle

The analog switches, multiplexers, and demultiplexers inside the PS301CPA have an electrically conductive channel between two terminals, and can be opened or closed by applying a voltage to its control terminal. The multiplexer is then used to switch between different types of signals, such as electrical and optical signals, while the demultiplexer can be used to direct the signal flow from a single source to multiple destinations.The circuit used by the PS301CPA has been designed such that all the inputs are filtered and regulated to ensure that the signal will remain clean and stable over its range. The multiplexer and demultiplexer can be programmed through a set of input switch signals, which determine the direction of the signal flow.In addition, the PS301CPA can be used for automatic gain control, and all of the analog switches are able to be switched with a low voltage, low current, and low noise operation. The PS301CPA is ideal for applications that demand high performance while still providing reliable operation.
