Kanalog - JP12 Low Voltage ADC

Post by matemos » Sun Jun 03, 2018 8:39 pm

Hi All,

I'm looking for an additional information regarding Kanalog JP12 connector specifically extra low voltage analog inputs (IN0-IN3)
- How do I address them in C program?
- What is their resolution?
- What reference voltage is applied to the ADC ?
- Is there a possibility to watch these variables over CONSOLE ?

Unfortunately my set up gone already to client and I have no testing boards to get new features prepared. I have to base on raw information.

Thanks
Mat

This was a duplicate question. I pasted the previous response below for reference:

Hi Mat,

ADC channels 0-3 have internal low voltage inputs exposed as signals IN0-IN3. Instead of driving the normal terminal inputs with a voltage range of +/- 10V. The INx pins may be driven with low voltage (0V - 3V) signals with an input impedance of ~10K ohms. This may allow higher resolution with low voltage signals. Caution should be used as these are low voltage unprotected signal inputs.

You can read them from a C Program as ADC(0) through ADC(3)

or ADC0 through ADC3 via the Console Script commands

The voltage range is from 0V to 3.0V and corresponds to 0 to 4095 counts.
