6.9 Electrical Characteristics (continued)

minimum and maximum specifications apply from TA = –40°C to +125°C, VDD = 3.0 V to 5.5 V, and IN = –0.1 V to 2 V;

typical specifications are at TA = 25°C, and VDD = 3.3 V (unless otherwise noted)

(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:

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

℃).

(5)

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

℃).
