Output voltage drift versus temperature

The output voltage drift versus temperature is defined as the maximum variation of Vout with

respect to its value at 25 °C over the temperature range. It is calculated as follows:

with Tmin < Tamb < Tmax.

Figure 18 provides a graphical definition of the output voltage drift versus temperature. On

this chart, Vout is always within the area defined by the maximum and minimum variation of

Vout versus T, and T = 25 °C is considered to be the reference.
