The measuring range is limited by sensitivity, offset and supply voltage rails of the device.
Offset specified as Voffset = Vout(@0 °) [V].
+15 V supply voltage used in calibration and testing.
Offset calibration error specified as Offset_Calib_error = arcsin(Offset_Calib_error_in_g) [ ° ],
Offset_Calib_error_in_g = {Vout(@0 °) – 2.5 V} / Vsens [g], Vsens=11.46 V/g.
Offset temperature error specified as
Offset_Error_@_temp. = arcsin(Offset_Error_@_temp_in_g) [ ° ],
Offset_Error_@_temp_in_g = {Vout @ temp. – Vout @ room temp.} / Vsens [g], Vsens=11.46 V/g.
Sensitivity target in calibration Vsens _nom 11.46 V/g (--> 200 mV/°)
Sensitivity specified as Vsens = {Vout(@+10 °) - Vout(@+10 °)}/(2*sin(10 °) g) [V/g].
Note 7.
Note 8.
Note 9.
Sensitivity calibration error specified as
Sensitivity_calibr_error = {Vsens - Vsens_nom} / Vsens_nom x 100 % [%],
Vsens_nom = nominal sensitivity.
Sensitivity temperature error specified as
Sensitivity_temp_error = {Vsens @ temp – Vsens @ room temp} / Vsens @ room temp} x 100 % [%].
From best fit sine-function to output through –10 ° and +10 °.
