{"product_id":"sparkfun-mikroe-analog-mux-4-click","title":"SparkFun MIKROE Analog MUX 4 Click","description":"\u003cp\u003eAnalog MUX 4 Click is a compact add-on board that switches one of many analog inputs to one digital output. This board features the TMUX1308, a general-purpose 8:1 single-ended CMOS multiplexer (MUX) from Texas Instruments. The TMUX1308 has an internal injection current control which eliminates the need for external diode and resistor networks to protect the switch and keep the input signals within the supply voltage. It also supports bidirectional analog and digital signals ranging from 0 to 5V, alongside several protection features allowing a reliable operation and protecting the device from potential damage. This Click board� is suitable for various applications, from industrial to instrumentation, consumer, communications, and more.\u003c\/p\u003e \u003cp\u003eAnalog MUX 4 Click as its foundation uses the TMUX1308, a general-purpose 8:1 single-ended CMOS analog multiplexer from Texas Instruments. The TMUX1308 multiplexer allows for multiple inputs\/sensors to be monitored with a single AN pin of the mikroBUS� socket supporting bidirectional analog and digital signals ranging from 0 to 5V. It has an internal injection current control eliminating the need for external diode and resistor networks to protect the switch, keeping the input signals within the supply voltage. The internal injection current control circuitry allows signals on disabled signal paths to exceed the supply voltage without affecting the signal of the enabled signal path.\u003c\/p\u003e \u003cp\u003eAlongside internal injection current control, the TMUX1308 also has another protection feature, called Break-before-make delay, which represents a safety feature preventing two inputs from connecting when the device is switching. The output first breaks from the ON-state switch before connecting with the next ON-state switch. This time delay between the break and the make is known as the break-before-make delay.\u003c\/p\u003e \u003cp\u003eThis 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 TMUX1308. It also provides three address signals, labeled from A0 to A2 and routed to the PWM, INT, and RST pins of the mikroBUS� socket, that control the switch configuration and determine the activation of the desired analog input channel based on their setup. Also, each analog input has a jumper for its hardware activation or deactivation and capacitors for additional filtering of the input channels.\u003c\/p\u003e \u003cp\u003eThis 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.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: Analog, GPIO\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUS�\u003c\/li\u003e \u003cli\u003eDimensions: 57.15 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003cli\u003eSupply Voltage: Min. 3.3V, Max. 5V\u003c\/li\u003e \u003cli\u003eAnalog Input Range: Min. 0V, Max. 5V\u003c\/li\u003e \u003cli\u003eON-State Resistance: 195Ω\u003c\/li\u003e \u003cli\u003eOperating Temperature Range: Min. -40°C, Typ. +25°C, Max. +120°C\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/a\/e\/4\/5\/0\/Schematic-20657-MIKROE_Analog_MUX_4_Click.PDF\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/7\/8\/2\/6\/TMUX1308_datasheet.pdf\"\u003eTMUX1308 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/libstock.mikroe.com\/projects\/view\/4683\/analog-mux-4-click\"\u003eLibStock\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40531139395669,"sku":"20657:COM-20657:spark","price":1855.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/20657_-_MIKROE_Analog_MUX_4_Click_2.jpg?v=1678248949","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-analog-mux-4-click","provider":"Tanotis","version":"1.0","type":"link"}
