Hardware: nrf52 DK Software: SDK v13
I want to use SAADC to sample some analog data (main function of my device), but It seems to be noisy. In attachment spreadsheet with chart and recorded data.
Reference = VDD/4, input = VDD, gain = 1/5, sampling triggered by app_timer with interval 200 ms.
Is it normall for nrf52 to have as much noise as I have?
