Are you aware of the limited input voltage range of ADC? As far as the specifications go, they seem to cover what I am trying to do: ADC input span is 0.8 FS to 2.1 FS (so, the maximum input range in the 20 mV nominal input range is 42 mV). Absolute AIN voltage limits are Agnd - 0.03 V to Avdd + 0.03 mV. (the lowest voltage I am trying to measure is -8.8 mV, well above the -30 mV given in the datasheet) |
