Reducing bandwidth below 0.01 Hz does not result in further noise improvement. 6 Self-test mismatch is described as (ST2 + ST1)/((ST2 − ST1)/2). 7 Scale factor for a change in temperature from 25°C to 26°C. VTEMP is ratiometric to VRATIO. See the section for more information. Temperature Output and Calibration |
