The EVAL-ADXL001 is a simple evaluation board that allows
users to quickly evaluate the performance of the ADXL001
vibration sensor. The EVAL-ADXL001 is specifically designed
to mount on to a mechanical shaker and is constructed of an
extra thick PCB, measuring 0.8 inches square. Screw holes are
supplied for rigid mounting to the shaker block. This design
allows users to easily evaluate the full performance range of the
ADXL001 vibration sensor without having to solder the device
to a separate test board. Solder pads are included that allow
users to implement their own application-specific low-pass
filter on the output of the device.
NOTES

CIRCUIT DESCRIPTION
0.8"
The schematic for the EVAL-ADXL001 is shown in Figure 1.
This circuit was designed to allow for a user-configurable lowpass 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 EMI rejection.

VDD and VDD2 are shorted together internally on the PCB. This is
consistent with normal device operation.
The board layout of the EVAL-ADXL001 is shown in Figure 2
and the parts list for the EVAL-ADXL001 is shown in Table 1.
As delivered, there is no bandwidth limit set for the ADXL001.
It is recommended that a ~75 kHz low-pass filter be added to
mitigate high frequency noise outside of the vibration band of
interest.
