Inclinometer
Note 1.

Note 4.
Note 5a.
Note 5b.
Note 6a.
Note 6b.
For maximum accuracy the supply voltage should be 5
±
0.05 V.
100nF supply filtering capacitor should be used.
The measuring range is limited by sensitivity, offset and supply voltage rails of the device.
Measuring direction parallel to mounting plane, arrow showing positive direction.
Offset specified as Voffset = Vout(0g) [ V ]. See note 12.
Sensitivity specified as Vsens = {Vout(+0.26g) - Vout(-0.26g)}/0.52 [ V/g ]. See note 12
Sensitivity specified as Vsens = {Vout(+0.5g) - Vout(-0.5g)}/1 [ V/g ]. See note 12
Offset calibration error specified as Offset_Calib_error = {Vout(0g) – Vdd/2} / Vsens [ g ].
Offset temperature error specified as Offset Error @ temp. = {Vout @ temp. – Vout @ room temp.}
/ Vsens [ g ]
Vsens = Nominal sensitivity. See note 12.
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 error @ temp = { [Vsens @ temp –Vsens @
room temp] / Vsens @ room temp x 100% [ % ]. See note 12.
Note 7a.
Note 7b.
Note 8.
Note 9.
From straight line through sensitivity calibration points.
The output has true DC (0Hz) response.
Note 10.
The ratiometric error is specified as:
Note 11.
The cross-axis sensitivity determines how much inclination / acceleration, perpendicular
to the measuring axis, couples to the output. The total cross-axis sensitivity is the geo-
metric sum of the sensitivities of the two axis which are perpendicular to the measuring
axis.
In addition, supply voltage noise couples to the output due to the ratiometric nature of the
accelerometer.
Factory calibration value.
Power continuously connected.
Is valid between angles 0° to 1°.

Note 13.
Note 14.
Note 15.

Parameters marked as D are measured in differential mode using external differential amplifier. The performance of selected amplifier may have an effect to some parameters.
Differential signal is determined as a Out_diff = Out_1 – Out_2 (pin 11 – pin 5).
