(1) The typical value includes one standard deviation (sigma) at nominal operating conditions.
(2) This parameter is input referred.
(3) THD is the ratio of the rms sum of the amplitudes of first five higher harmonics to the amplitude of the fundamental.
(4) Offset error temperature drift is calculated using the box method, as described by the following equation:
TCVOS = (ValueMAX - ValueMIN) / TempRange
(5) Gain error temperature drift is calculated using the box method, as described by the following equation:
TCEG (ppm) = (ValueMAX - ValueMIN) / (Value(T=25℃) x TempRange) x 106
