I have spikes on my DAQ mesure

[apc22]

Hello, I have been developing a project of DAQ based on ArduinoDUE (with USBserial - Native USB), the ADC is MAX11040k (that is conected with SPI with Arduino), and HMI with LabView.
In this moment I can consider that the project is almost finished. I need to solve some problems before finish it.

One of them is that in this moment my mesure have occasionally spikes (or peaks) that afect it (unwanted spikes because the sensor doesn't read this value that is near to the max ADC value). I'm reading 24 channels with a sample rate of 2ksps and I have this result:

Someone knows what can I do to correct it?

Very limited information to provide guidance.

First, you need to narrow down the issue whether the issue is in your LabVIEW code or firmware on Arduino or communication method or actual signal or some part in the signal conditioning side.
