NOTES:
4. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V_OUT is divided by the
temperature range; in this case, -40°C to +125°C = +165°C.
5. Thermal Hysteresis is the change of V_OUT measured @ T_A = +25°C after temperature cycling over a specified range, ΔT_A. V_OUT is read initially
at T_A = +25°C for the device under test. The device is temperature cycled and a second V_OUT measurement is taken at +25°C. The difference
between the initial V_OUT reading and the second V_OUT reading is then expressed in ppm. For Δ T_A = +165°C, the device under test is cycled
from +25°C to +125°C to -40°C to +25°C.
6. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/sqrt(1kHrs).
