(1) The typical value includes one standard deviation ("sigma") at nominal operating conditons.

(2) This parameter is input referred.

(3) THD is the ratio of the rms sum of the amplitues 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:
TCV_OS = (V_OS,MAX - V_OS,MIN) / TempRange where V_OS,MAX and V_OS,MIN refer to the maximum and minimum V_OS 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℃).
