Key Features
Overview
La carte Click Board™ MUX 5 est une carte complémentaire compacte qui contient une solution de multiplexage précise. Cette carte est équipée du MAX14661, un multiplexeur analogique à double canal contrôlé en série d'Analog Devices, permettant de connecter simultanément n'importe laquelle des 16 broches à l'une ou l'autre des broches communes dans n'importe quelle combinaison. Le MAX14661 est doté de la fonctionnalité Beyond-the-Rails™ qui permet de transmettre des signaux ±5,5 V avec n'importe quelle configuration d'alimentation ainsi qu'une interface hôte configurable qui prend en charge les communications série SPI et I2C. Les deux modes offrent un contrôle individuel de chaque commutateur indépendant afin que n'importe quelle combinaison de commutateurs puisse être appliquée. Cette carte Click™ est conçue pour prendre en charge diverses applications de multiplexage telles que les diagnostics système, l'acquisition de données, la commutation de signaux et bien d'autres encore.
La carte Click Board™ MUX 5 est supportée par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.

How Does The MUX 5 Click Board™ Work?
The MUX 5 Click Board™ is based on the MAX14661, a serially controlled, dual-channel analog multiplexer from Analog Devices. It allows any of the 16 pins to be connected to any of the common pins, routed to the AN or INT pins of the mikroBUS™ socket, simultaneously in any combination. The MAX14661 features Beyond-the-Rails™ capability, which mainly simplifies an analog design by eliminating the need for multiple power rails and allows ±5.5V signals to be passed with any supply configuration. It integrates bias circuitry to switch high-voltage (±25V) signals while operating from a low-voltage supply with low on-resistance and fast bandwidth speeds. This Click board™ is ideal for audio and data multiplexing, interface termination, switching, industrial measurement, and instrumentation systems.

The MAX14661 allows using both I2C and SPI interfaces. Both modes provide individual control of each independent switch so that any combination of switches can be applied. The selection can be made by positioning SMD jumpers labelled as COMM SEL in an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive. While the I2C interface is selected, the MAX14661 allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL.
The MUX 5 Click Board™ also possesses an additional active-low shutdown pin, routed to the RST pin on the mikroBUS™ socket. When this pin is set to a low logic state, all registers are cleared, all switches are open, and the serial interface is not functional. All switch connections are open and tolerant of the full ±5.5V specified signal range. It is good to address that the MAX14661 consumes minimal power in this mode.
The MUX 5 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
