Basic knowledge of analog switches

    Analog switches typically use one of the following configurations:

    Single throw

    Single throw multiple throw

    Multi pole multi throw or multiplexer.
    The number of poles represents the number of common terminals (or active contacts), while the number of rolls represents the number of spare terminals that can be connected to the common side. The switches in each package can be single switch, double switch, or multiple switches (usually even). These switches can be activated individually or simultaneously. The Enzhipu high-performance analog switch product portfolio includes devices using each of the above configurations. The NX3 series offers all standard configurations of SPST, SPDT... single, dual, and quad.

    The following figure adds the high-performance analog switch part numbers corresponding to each function.

    In some applications, analog switches are located at the interface between low-voltage ASICs and higher power voltage components. In order to activate the switch correctly, a voltage converter (or level converter) is usually used on the selection pin to ensure that the activation threshold is met. Enzipu analog switches provide a complete range of devices that integrate converter functions, thereby saving component quantity, PCB space, and reducing overall system costs.

    The "T" in the part number distinguishes analog switches with integrated converter functionality. Some part numbers of the low ohm NX3 series switches are highlighted in this slide. The ‘G‘ section does not include translation functionality.
