ADXL150/ADXL250
REV. 0
Zero
g
Bias Level:
The output voltage of the ADXL150/
ADXL250 when there is no acceleration (or gravity) acting
upon the axis of sensitivity. The output offset is the difference
between the actual zero
g
bias level and (V
S
/2).
Polarity of the Acceleration Output
The polarity of the ADXL150/ADXL250 output is shown in
Figure 1. When its sensitive axis is oriented to the earth’s gravity
(and held in place), it will experience an acceleration of +1
g
.
This corresponds to a change of approximately +38 mV at the
output pin. Note that the polarity will be reversed if the package
is rotated 180
°
. The figure shows the ADXL250 oriented so that
its “X” axis measures +1
g
. If the package is rotated 90
°
clock-
wise (Pin 14 up, Pin 1 down), the ADXL250’s “Y” axis will now
measure +1
g
.

Acceleration Vectors
The ADXL150/ADXL250 is a sensor designed to measure
accelerations that result from an applied force. It responds to
the component of acceleration on its sensitive X axis (ADXL150)
or on both the “X” and “Y” axis (ADXL250).
GLOSSARY OF TERMS
Acceleration:
Change in velocity per unit time.
Acceleration Vector:
Vector describing the net acceleration
acting upon the ADXL150/ADXL250.
g
:
A unit of acceleration equal to the average force of gravity
occurring at the earth’s surface. A
g
is approximately equal to
32.17 feet/s
2
or 9.807 meters/s
2
.
Nonlinearity:
The maximum deviation of the ADXL150/
ADXL250 output voltage from a best fit straight line fitted to a
plot of acceleration vs. output voltage, calculated as a % of the
full-scale output voltage (at 50
g
).
Resonant Frequency:
The natural frequency of vibration of
the ADXL150/ADXL250 sensor’s central plate (or “beam”). At
its resonant frequency of 24 kHz, the ADXL150/ADXL250’s
moving center plate has a slight peak in its frequency response.
Sensitivity:
The output voltage change per
g
unit of accelera-
tion applied, specified at the V
OUT
pin in mV/
g.
Total Alignment Error:
Net misalignment of the ADXL150/
ADXL250’s on-chip sensor and the measurement axis of the
application. This error includes errors due to sensor die align-
ment to the package, and any misalignment due to installation
of the sensor package in a circuit board or module.
Transverse Acceleration:
Any acceleration applied 90
°
to the
axis of sensitivity.
Transverse Sensitivity Error:
The percent of a transverse
acceleration that appears at V
OUT
.
Transverse Axis:
The axis perpendicular (90
°
) to the axis of
sensitivity.
