Note 1. Note 2. Note 3. Note 4. Note 5. Note 6. 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 °.
