1 Parameter is linearly ratiometric with V
RATIO.
2 Measurement range is the maximum range possible, including output swing range, initial offset, sensitivity, offset drift, and sensitivity drift at 5 V supplies.
3 From +25°C to −40°C or +25°C to +105°C.
4 Adjusted by external capacitor, C
OUT. Reducing bandwidth below 0.01 Hz does not result in further noise improvement.
5 Self-test mismatch is described as (ST2 + ST1)/((ST2 − ST1)/2).
6 Scale factor for a change in temperature from 25°C to 26°C. V
TEMP is ratiometric to VRATIO. See the Temperature Output and Calibration section for more information.
7 Based on characterization.
