ADXL1001/ADXL1002 data sheet
GENERAL DESCRIPTION
The EVA L-ADXL1001Z and EVA L-ADXL1002Z are simple
evaluation boards that allow users to quickly evaluate the
performance of the ADXL1001 and ADXL1002 vibration
sensors. The E VA L-ADXL1001Z and EVA L-ADXL1002Z are
specifically designed to mount onto a mechanical shaker and are
constructed of an extra thick printed circuit board (PCB),
measuring 0.8 inches square. Screw holes are supplied for rigid
mounting to the shaker block. This design allows users to
evaluate the full performance range of the ADXL1001 or
ADXL1002 vibration sensor without having to solder the device
to a separate test board. A simple RC low-pass filter is provided
at the output with a −3 dB bandwidth of about 20 kHz.
Components can be replaced to allow users to implement their
own application specific low-pass filter on the output of the
device.
Full details on the microelectromechanical systems (MEMS)
ADXL1001/ADXL1002 accelerometers are provided in the
ADXL1001/ADXL1002 data sheet, available from Analog
Devices, Inc., which must be consulted in conjunction with this
evaluation board user guide.

EVALUATION BOARD HARDWARE
CIRCUIT DESCRIPTION
The schematics for the EVA L-ADXL1001Z and E VA L -
ADXL1002Z are shown in Figure 3 and Figure 4. This circuit
was designed to allow a user configurable low-pass filter on the
device output. When no low-pass filter is needed, users must
short the R1 solder pads together, and it is recommended that a
bypass capacitor (22 nF) be placed on C2 for improved
electromagnetic interference (EMI) rejection.
The board layouts of the EVA L-ADXL1001Z and EVA L-
ADXL1002Z are shown in Figure 1 and Figure 2, and the bill of
materials list for the EVA L -ADXL1001Z and EVA L-ADXL1002Z is
shown in Table 1. As delivered, the bandwidth limit of the
evaluation boards is set by the external RC filter at about
20 kHz. It is recommended that additional filtering, such as a
<75 kHz low-pass filter, be added to mitigate high frequency
noise outside of the vibration band of interest.
SPECIAL NOTES ON HANDLING
The E VA L-ADXL1001Z and E VA L -ADXL1002Z are not reverse
polarity protected. Reversing the power supply or applying
inappropriate voltages to any pin may damage the E VA L -
ADXL1001Z and EVA L -ADXL1002Z.
