Part Number: ADS1220 Hello, I want to ask following question: I have requirements of having a SPS at >=300 SPS. If i choose PGA = 1 and SPS = 330, I can expect 17.7 ENOB as written in the data sheet. But if I have two inputs that is being multiplexed, is it in fact a sampling rate of 175 SPS for each inputs? So the sampling rate is being divided by the inputs. If that's the case, Would I have to choose SPS = 600, in order to have 300 SPS of each input? Also the ENOB is being reduced as function of the sampling rate. Is it possible to obtain a higher ENOB with same SPS, using an external clock? Best regards, Sadoun Anayati
