NOTES:
10. 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.
11. Thermal Hysteresis is the change of VOUT measured @ TA = +25°C after temperature cycling over a specified range, ïTA. 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 ï TA = +125°C, the device under test is cycled from +25°C to
+85°C to -40°C to +25°C.
12. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/ï1khrs.
13. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
