Note 1 The noise density of CAHH1G and CA1H1G is 30 µg/ Hz, the noise density of C23H1A and C28H1A
is 20 µg/ Hz.
Note 2 The measuring range is limited by sensitivity, offset and supply voltage rails of the device.
Note 3 Measuring direction parallel to the mounting plane.
Note 4 Vertical versions in +1 g position, i.e. arrow up: horizontal versions pins down (+0 g)
Note 5a Sensitivity specifi ed as [Vout (+1 g) - Vout(-1 g)] / 2 [V/g] .
Note 5b Sensitivity specifi ed as [Vout (+0.5 g) - Vout(-0.5 g)][V/g] .
Note 6 Zero point error specifi ed as (Vout (+0 g) - Vdd/2) / Vsens [g] (room temp. error included);
Vsens = Nominal sensitivity.
Note 7 Typical tolerance, not 100 % tested.
Note 8a Sensitivity error specifi ed as {{[Vout (+1 g) -Vout (-1 g)] / 2} -Vsens} / Vsens x 100 % [%] (room
temp. error included); Vsens = Nominal sensitivity.
Note 8b 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.
Note 9a Relative to straight line between ±1 g.
Note 9b Relative to straight line between ±0.5 g.
Note 9c In inclinometer applications a correction based on the angular error resulting from cross-axis
sensitivity around the inclination angle reduces non-linearity.
Note 10 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 11 The output has true DC (0 Hz) response.
Note 12 Supply voltage noise also couples to the output, due to the ratiometric (output proportional
to supply voltage) nature of the accelerometer.
Note 13 Self test not recommended.
The ratiometric error is specifi ed as:
