GENERAL DESCRIPTION
The ADXL105EM, ADXL150EM, and ADXL190EM evaluation
modules provide a complete acceleration measurement system in
a low cost package. These modules simplify the evaluation and
testing of our ADXL105/ADXL150/ADXL190/ADXL250
monolithic accelerometer ICs.
The ADXL105, ADXL150, ADXL190 (single) and ADXL250
(dual axis) accelerometers offer low noise and high signal-to-noise
ratios. In addition, the scale factor and 0
g
output level are both
ratiometric to the power supply so the accelerometer and any fol-
lowing circuitry (such as an ADC, etc.) will track each other if
the supply voltage varies.
Each module contains one or more ADXL105, ADXL150, or
ADXL190 series 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 sup-
ply. The module should be attached (i.e., screwed or glued
down) securely to the object being measured, taking care that
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 our third party
partners. See our web site at:

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
.
4
Nonlinearity is the deviation from a best fit straight line at full scale.
5
Transverse sensitivity is error measured in the primary axis output created by forces induced in the orthogonal axis. 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).
6
All frequency break points are –3 dB, single pole, –6 dB per octave roll-off.
