Hi Lagva, One clarification, the THP210 should be operated with +/-2.5V supplies, same supplies used for the ADC. The GND pin of the 4.096V reference and ADC REFN pin connects to -2.5V. Route the trace of the ADC REFN pin to the GND pin of the reference, then connect to -2.5V. This avoids picking up noise and signal induced currents from the -2.5V supply. Thank you for the paper, it is interesting. I will take time to read it and supply comments if warranted. Regards, Mark
