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

(2) This parameter is input referred.

(3) 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℃).

(4) 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℃).
