Hello dear Ti friends:
In the ADS1299 datasheet, it states that the SNR of the ADS1299 is 121 dB. However, I estimate that, theoretically, the SNR of the ADS1299 can only reach 20×log(375000×0.8/1.61)= 105 dB. But the datasheet claims it is 121 dB.
And we bought the board ADS1299EEGFE-PDK, its SNR also falls far short of 121 dB，only 86dB.
I would like to ask, how did you calculate to reach 121 dB?
Thank you!
