Please tell me how the AD value changes according to the ADC_DelSig buffer gain (1, 2, 4, 😎 setting.
gain = 1-> gain = 2-> gain = 4-> gain = 8
I thought the AD value would be 2x, 4x, 8x,
It does not actually change linearly.
It became 0x1556, 0x2CBD, 0x3387, 0x3652.
ADC_DelSig の buffer gain (1, 2, 4, 8)設定によって どのように AD値が変化するのか教えてください。
gain =1 --> gain =2 --> gain =4 --> gain =8 と変更すると
AD値が 2倍、 4倍 、 8倍 となると 考えていたのですが、
実際には リニアに変化しません。
0x1556 、0x2CBD、 0x3387 、 0x3652 と なりました。
Solved! Go to Solution.

Hi,
Please note that you cannot set ADC buffer gain to 2x, 4x, 8x for all types of voltage ranges that the ADC will support. Please find the attached snip which is taken from Delta sigma ADC component datsheet.
If you are following it and still you are facing issues means please come back.
Thanks
