Hi, I recorded the voltage from the ADC of CN0338 but I saw that there was oscillation which makes measurement varies a lot in my high accuracy demand application. I just wonder if you have any clue what happens to the board ? The blue line is the peak to peak voltage from the REF channel. The orange is the peak to peak voltage from the ACT channel. I used the average algorithm to acquire the signal from the thermopile.
