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 125

℃).

(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 125

℃).

(5)

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