Part Number: ADS131E08EVM-PDK Hi Team, We want to calculate or check the ENOB for ADS131E08 EVM-PDK kit. For particular PGA Gain and Data rate we will have certain ENOB as mentioned in Table 1(Pg. no 13) of ADS131E08S Datasheet. Also on ADS131E08 EVM software we can check the SNR so we tried to calculate the ENOB from SNR using this formula: ENOB = (SNR – 1.76) / 6.02 dB. Following readings we got & which are not matching with Table 1 (Pg. no 13) of ADS131E08S Datasheet. As input voltage (Vpp) increases SNR decreases so ENOB also decreases. Is our approach is correct or not? Regards, Tejaswini
