CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are at

is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
4. Post-reflow drift for the ISL21009 devices will range from 100µV to 1.0mV based on experimental results with devices tested in sockets and also
on FR4 multi-layer PC boards. The design engineer must take this into account when considering the reference voltage after assembly.

5. 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.
6. 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.
7. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/√(1kHrs).
