THERMAL HYSTERESIS
Thermal hysteresis is the voltage difference induced on the
reference voltage by sweeping the temperature from ambient
to cold, to hot, and then back to ambient.
Thermal hysteresis data is shown in Figure 49. It is measured by
sweeping temperature from ambient to −40°C, then to +105°C,
and returning to ambient. The VREF delta is then measured between
the two ambient measurements and shown in blue in Figure 49.
The same temperature sweep and measurements are immediately
repeated, and the results are shown in red in Figure 49.
