NOTES:
7. 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.
8. Thermal Hysteresis is the change of VOUT measured @ TA = +25°C after temperature cycling over a specified range, ÎTA. 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 ΠTA = +125°C, the device under test is cycled from +25°C to +85°C to -40°C to +25°C.
9. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately
10ppm/â1khrs
10. 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.
