(1) This parameter is input referred.

(2) The typical value includes one sigma statistical variation.

(3) Integral nonlinearity is defined as the maximum deviation from a straight line passing through the end-points of the ideal ADC transfer
function expressed as number of LSBs or as a percent of the specified linear full-scale range FSR.

(4) Offset error temperature drift is calculated using the box method, as described by the following equation:
TCE_O = (E_O,MAX – E_O,MIN) / TempRange where E_O,MAX and E_O,MIN refer to the maximum and minimum E_O values measured within the temperature range (–40 to 125℃).

(5) Gain error temperature drift is calculated using the box method, as described by the following equation:
TCE_G (ppm) = ((E_G,MAX - E_G,MIN) / TempRange) x 10⁴ where E_G,MAX and E_G,MIN refer to the maximum and minimum E_G values (in %) measured within the temperature range (–40 to 125℃).

(6) THD is the ratio of the rms sum of the amplitudes of first five higher harmonics to the amplitude of the fundamental.
