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. VTEMP is ratiometric to VRATIO. See the Temperature Output and Calibration section for more information. 7 Based on characterization. Rev.
