Overview
Das Analog MUX 5 Click Board™ ist eine kompakte Zusatzplatine, die einen von vielen Eingängen auf einen Ausgang umschaltet. Diese Platine verfügt über den MAX4634, einen schnellen, Niederspannungs-4-Kanal-CMOS-Analogmultiplexer von Analog Devices. Dieser Niederspannungsmultiplexer arbeitet über beide mikroBUS™-Stromschienen und verfügt über einen maximalen Einschaltwiderstand (RON) von 4 Ω. Die CMOS-Schalterkonstruktion ermöglicht die Verarbeitung analoger Signale innerhalb des Versorgungsspannungsbereichs. Es zeichnet sich außerdem durch eine einfache Verwaltung aus, nur durch ein paar Signale von der mikroBUS™-Buchse. Dieses Click Board™ ist für verschiedene Anwendungen geeignet, von Industrie und Instrumentierung bis hin zu Medizin, Verbraucher, Kommunikation und mehr.
Das Analog MUX 5 Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.
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.
