Hi Bryan, First of all thanks for replaying! You are right, the data is different between CHID, but the thing is that in the MISO signal I am getting data (the 3 bytes of data) in the CHID where I have an input signal set to off (AIN8 -> CHID="10000") Here is more explanation about the problem I have... According to the CHID I am filling a FIFO with the objective of collecting a certain amount of data (so I have 2 FIFOs, one for each CHID) and when it is already full and downloaded you can see how the signal of both FIFOs seems to be the same with a slight Delay or Phase Shift, as can be seen in the attached image, I mean that they are not the same but they keep the same form, but remember that one of the AINs is connected to an input signal off. So apparently, since the MISO signal for both CHID sends converted data, internally in the ADC what enters through AIN0 is taken as if it were entering in the same way through AIN8 And with respect to AINCOM pin, it is grounded
