DESCRIPTION
The ADXLEM Series of evaluation modules provides a com-
plete acceleration measurement system in a low cost package.
The modules simplify the evaluation and testing of our ADXL50
and ADXL05 monolithic accelerometer ICs. Each module con-
tains one or more accelerometers precalibrated to a convenient
output scale factor with onboard low-pass filtering.
All that is required to use these modules is a +5 volt power
supply. The module should be attached (i.e., screwed or glued

the axis of sensitivity, indicated by the large arrow on the top of
the module, is aligned with the expected acceleration.
Modules are available in other package styles (such as rug-
gedized metallic box) and in other g ranges from NGT Tech-
nology, 3 Cross Road, LaGrangeville, NY 12540-5705,

NOTES
1
All frequency break points are 3 dB, single pole, 6 dB per octave roll-off.
2
Nonlinearity is the deviation from a best fit straight line at full scale.
3
Transverse sensitivity is error measured in the primary axis output created by forces induced in the orthogonal axis.
4
Zero g Drift is specified as the typical change in 0 g level from its initial value at +25
C to its worst case value at T
MIN
or T
MAX
.
5
Consult factory for availability of higher bandwidth version of ADXL05EM modules.
6
Transverse sensitivity error is primarily due to the effects of misalignment (i.e., much of it can be tuned out by adjusting the package orientation).
Specifications subject to change without notice.
