Hi Adam, Thanks for your detailed description! I’m interested to see your pictures, can you try to click on the rich formatting link and inserting them as picture. About your observed behavior, I’m worried if you see some kind of noise from your setup. Using a normal power supply as ADC input signal can easily catch some noise sources, especially if your using long cables which are not twisted. So one proposal from me would be to check your setup with a battery as ADC input signal. I know that you checked the input signal with a multimeter, but a multimeter measures due to a longer measurement time an average value. The ADC should be much faster depending on you sample time configuration. Best regards, Tobias
