(1) This parameter is input referred.
(2) 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.
(3) Offset error temperature drift is calculated using the box method, as described by the following equation:
TCEO = (EO,MAX – EO,MIN) / TempRange where EO,MAX and EO,MIN refer to the maximum and minimum EO values measured within the temperature range (–40 to 105℃).
(4) Gain error temperature drift is calculated using the box method, as described by the following equation:
TCEG (ppm) = ((EG,MAX - EG,MIN) / TempRange) x 104 where EG,MAX and EG,MIN refer to the maximum and minimum EG values (in %) measured within the temperature range (–40 to 105℃).
(5) THD is the ratio of the rms sum of the amplitudes of first five higher harmonics to the amplitude of the fundamental.
(6) Maximum values, including temperature drift, are ensured over the full specified temperature range.
