Note 1. The measuring range is limited by sensitivity, offset and supply voltage rails of the device.
Note 2. Measuring direction parallel to mounting plane.
Note 3. Vertical versions in +1g position, i.e. arrow up; horizontal versions pins down (+0g).
Note 4a. Zero point error specified as (Vout (+0g) - Vdd/2) / Vsens [g] (room temp. error included); Vsens = Nominal sensitivity.
Note 4b. Zero point error specified as [Vout (+1g) - Vdd/2] / Vsens [g] (room temp. error included); Vsens = Nominal sensitivity.
Note 5. Sensitivity specified as [Vout (+1g) - Vout(-1g)] / 2 [V/g] .
Note 6. Sensitivity error specified as {[Vout (+1g) -Vout (-1g)] / 2 -Vsens} / Vsens x 100% [%] (room temp. error included); Vsens = Nominal sensitivity.
Note 7. Relative to straight line between ±1g.
Note 8. The cross-axis sensitivity determines how much acceleration, perpendicular to the measuring axis, couples to the output. The total cross-axis sensitivity is the geometric
sum of the sensitivities of the two axes, which are perpendicular to the measuring axis.
Note 9. The output has true DC (0Hz) response.
Note 10. Supply voltage noise also couples to the output, due to the ratiometric (output proportional to supply voltage) nature of the accelerometer.
