The noise density of CAHH1G and CA1H1G is 30 µg/ Hz, the noise density of C23H1A and C28H1A

is 20 µg/ Hz.

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

Measuring direction parallel to the mounting plane.

Vertical versions in +1 g position, i.e. arrow up: horizontal versions pins down (+0 g)

Sensitivity speciﬁ ed as [Vout (+1 g) - Vout(-1 g)] / 2 [V/g] .

Sensitivity speciﬁ ed as [Vout (+0.5 g) - Vout(-0.5 g)][V/g] .

Zero point error speciﬁ ed as (Vout (+0 g) - Vdd/2) / Vsens [g] (room temp. error included);

Vsens = Nominal sensitivity.

Typical tolerance, not 100 % tested.

Sensitivity error speciﬁ ed as {{[Vout (+1 g) -Vout (-1 g)] / 2} -Vsens} / Vsens x 100 % [%] (room

temp. error included); Vsens = Nominal sensitivity.

Sensitivity error speciﬁ ed as {{[Vout (+0.5 g) -Vout (-0.5 g)] / 2} -Vsens} / Vsens x 100 % [%]

(room temp. error included); Vsens = Nominal sensitivity.

Relative to straight line between

In inclinometer applications a correction based on the angular error resulting from cross-axis

sensitivity around the inclination angle reduces non-linearity.

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.

The output has true DC (0 Hz) response.

Supply voltage noise also couples to the output, due to the ratiometric (output proportional

to supply voltage) nature of the accelerometer.

Self test not recommended.
