Understanding Voltage-Reference Temperature Drift
... This value is always positive and negative. So over the device's specified temperature range, we can guarantee that the reference will drift by less than ±875ppm of the initial value. This is shown graphically in Figure 2, where the data are very impressive for a SOT23-packaged device. The "box" is ...
