The measuring range is limited by sensitivity, offset and supply voltage rails of the device.

Offset specified as Voffset = Vout(@0°) [V].

+5V supply voltage used in calibration and testing.

See proposed connection of SCL1700 in picture 2.

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=8.595 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=8.595 V/g.

Sensitivity target in calibration 8.595 V/g (à 150 mV/°)

Sensitivity specified as Vsens = {Vout(@+10°) - Vout(@+10°)}/(2*sin(10°) g) [V/g].

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° (SINE COMPENSATED).
