I am sorry if it is rude or inappropriate to you, since I use the online translation site.
I am currently trying to perform an analog-to-digital conversion of 8 channels by selecting the auto sequence mode.
I have connected an oscillator as a pseudo-input and am sampling at 1kHz with a sine wave input, but when I graph the conversion results, I find that the signal is rattling.
Bit by bit analysis shows that more than 99% of the values from the 7th bit to the 10th bit are the same.
What could be the cause?
