REF
= 10.0 V, Conversion Rate = 100 kSPS unless otherwise noted. Values are post-calibration.

to T
MAX
after calibration at that temperature at nominal supplies.
3
Values shown are based upon calibration at +25°C with no additional calibration at temperature. Values shown are the typical variation from the value at +25 °C.
