    Tested at 12.5 MHz ADCCLK.
    All voltages listed in this table are with respect to V
    .
    TI specifies that the ADC will have no missing codes.
    1 LSB has the weighted value of 3.0/4096 = 0.732 mV.
    A single internal/external band gap reference sources both ADCREFP and ADCREFM signals, and hence, these voltages track
    together. The ADC converter uses the difference between these two as its reference. The total gain error listed for the internal reference
    is inclusive of the movement of the internal bandgap over temperature. Gain error over temperature for the external reference option will
    depend on the temperature profile of the source used.
    Voltages above V
    + 0.3 V or below V
    - 0.3 V applied to an analog input pin may temporarily affect the conversion of another pin.
    To avoid this, the analog inputs should be kept within these limits.
    TI recommends using high precision external reference TI part REF3020/3120 or equivalent for 2.048-V reference.
