NOTES:
9. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the
temperature range; in this case, -40°C to +85°C = +125°C.
10. Thermal Hysteresis is the change of VOUT measured @ TA = +25°C after temperature cycling over a specified range, ΔTA. VOUT is read initially at TA =
+25°C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25°C. The difference between the
initial VOUT reading and the second VOUT reading is then expressed in ppm. For Δ TA = +125°C, the device under test is cycled from +25°C to +85°C
to -40°C to +25°C.
11. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/
√1khrs
12. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
