    Looking for a simple USB analog to digital converter with existing support in a language like python

    Hey all, I was wondering if someone could point me to a component that fits this description. Id like a USB that plugs directly into a computer with voltage terminals and converts it into a digital representation that has existing support in a programming language to easily read in the data. The...

    Using Raspberry Pi Codec Zero HAT

    Hello, I have recently bought a Raspberry Pi Codec Zero to do audio processing. I have gone through all the documentation and set up all the necessary settings. When I run my codes, I get no input. So my questions are; How can you get access directly to the ADC? Maybe the ADC may have a way to...

    AC Current Measurment Strategy

    Hi All, We are busy with a project that takes measurements from a Current Transformer (CT) to track current usage in attached appliances. The CT is connected through an amplifier circuit to a micro-controller ADC pin. The AC wave (positive cycle only) is sampled at 100us intervals (there are a...

    Transferring audio by I2S

    Hello! My plan is to create a circuit, which would effectively transfer 6 channels of analog 16-bit audio signal to the other side without loosing quality or inducing some kind of interference. Cable length would be around 5 meters. This circuit would be used in automotive to substitute 6 RCA...

    ADC Error Calculation

    I am trying to determine DC errors for ADC128S102QML-SP. More specifically, I am referring to the gain error, offset error, INL error, and DNL error. It is a 12 bit ADC with a supply voltage of 5V. From the datasheet, I concluded the following: Offset error is 2.3 LSB which I believe...

    Quad 100k Digital Rheostat - Can it be wired for 300k?

    Hi, I have a Fairchild FL51x0 which has a control pin where the voltage at the pin is input to an 8 bit ADC with 2.5V reference. The pin sources 10uA current, so that an external resistor can be used to set the voltage (0-250k). I'd like to use a Digital Potentiometer/Rheostat. However, the...

    ADC for 8 Buttons

    Hi folks, for a uni project I’m creating a synth using an Arduino. I want to have at a minimum 8 buttons for an input but I’m restricted to using only 1 or 2 input pins. Therefore I wanted to use an ADC to convert the input to binary values. I wanted to use no IC’s if possible so tried using an...

    Accelerometer signal conditioning (ADC reading)

    Hello, I found a 3-axial accelerometer with +/-500g that has a +/-1.25V range. The bias voltage (0g) is at half of the reference given (It does not give negative voltage). If I'm supplying it with 3.3V, the bias voltage will be at 1.65V, so the range will be nominally 0.4V to 2.9V. I am to...

    How to convert ADC reading to analog current value in LTC6106

    I couldn't convert the ADC reading to its respective analog current value. I connected a microcontroller in the Vout to read the current, it will give an 8bit HEX value. The load is another microcontroller. The ADC reading in no-load is HEX00. (8-bit @ 3.3V) and LTC6106 for current sensing...
