2. 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 +125°C = +165°C.
3. 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 = +165°C, the device under test is cycled
from +25°C to +125°C to -40°C to +25°C.
4. FGA voltage reference long term drift is a logarithmic characteristic. Changes that occur after the first few hundred hours of operation are
significantly smaller with time, asymptotically approaching zero beyond 1,000 hours. Because of this decreasing characteristics, long term drift
is specified in ppm/√1kHrs.
