La carte Click Board™ Analog MUX 5 est une carte complémentaire compacte qui commute l'une des nombreuses entrées vers une sortie. Cette carte est équipée du MAX4634, un multiplexeur analogique CMOS quatre canaux basse tension rapide d'Analog Devices. Ce multiplexeur basse tension fonctionne à partir des deux rails d'alimentation mikroBUS™ et présente une résistance ON maximale de 4 Ω (RON). La construction du commutateur CMOS permet le traitement des signaux analogiques dans la plage de tension d'alimentation. Elle se caractérise également par un mode de gestion simple, uniquement via quelques signaux provenant de la prise mikroBUS™. Cette carte Click™ convient à diverses applications, de l'industrie et de l'instrumentation au médical, au grand public, aux communications, etc.
La carte Click™ Analog MUX 5 est prise en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The Analog MUX 5 Click Board™ Work?
The Analog MUX 5 Click Board™ as its foundation uses the MAX4634, a low-on-resistance, low-voltage analog multiplexer from Analog Devices. CMOS switch construction of the MAX4634 allows the processing of analog signals within its supply voltage range. It features 4Ω maximum ON-resistance (RON) and offers RON matching between switches to 0.3Ω maximum and RON flatness of 1Ω maximum ver the specified signal range. Also, all digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility with +5V operation.
The Analog MUX 5 Click Board™ communicates with MCU using several GPIO pins. It can be enabled or disabled through the EN pin routed to the CS pin of the mikroBUS™ socket; hence, offering a switch operation to turn ON/OFF power delivery to the MAX4634. It also provides two address signals, labelled as A0 and A1 and routed to the PWM and INT pins of the mikroBUS™ socket, that determine the activation of the desired analog input channel based on their setup while monitoring of that input analog signal is done using AN pin of the mikroBUS™ socket.
Each analog input has a jumper for its hardware activation or deactivation from R3 to R6 and capacitors for additional filtering of the input channels from C3 to C6. Proper power-supply sequencing is recommended for all CMOS devices. Before applying analog signals or logic inputs, always apply the power supply first, especially if the analog or logic signals are not current-limited.
The Analog 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 that contains easy-to-use functions and an example code that can be used, as a reference, for further development.

Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The Analog MUX 5 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
