(1) The typical value includes one standard deviation (sigma) at nominal operating conditions.
(2) This parameter is input referred.
(3) The typical value is at VDD1 = 3.3 V.
(4) THD is the ratio of the rms sum of the amplitues of first five higher harmonics to the amplitude of the fundamental.
(5) Offset error temperature drift is calculated using the box method, as described by the following equation:
TCVOS = (VOS,MAX - VOS,MIN) / TempRange where VOS,MAX and VOS,MIN refer to the maximum and minimum VOS values measured within the temperature range (–40 to 125℃).
(6) 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℃).
(7) Value is below measurement capability.
