Preliminary Technical Data
Parameter is linearly ratiometric with V
Measurement range is the maximum range possible, including output swing range, initial offset, sensitivity, offset drift, and sensitivity drift at 5 V supplies.
From +25°C to −40°C or +25°C to +105°C.
Adjusted by external capacitor, C
Self-test mismatch is described as (ST2 + ST1)/((ST2 − ST1)/2).
Scale factor for a change in temperature from 25°C to 26°C. V
