Hi David, Are you calibrating the ADC? The TLV structure contains calibration values for the ADC. Also, the analog input voltage range must be within the selected reference voltage range VR+ to VR- for valid conversion results. Keep in mind that the external source resistance and external parasitic capacitance affects the minimum sampling time, as discussed in Section 20.2.6.3 in the Technical Reference Manual.
