DESCRIPTION
The EVAL-ADXL335Z is a simple evaluation board that allows
quick evaluation of the performance of the ADXL335 three-axis
accelerometer. The EVAL-ADXL335Z has a 6-pin, 0.1 inch
spaced header for access to all power and signal lines that the
user can attach to a prototyping board (breadboard) or wire
using a standard plug. Four holes are provided for mechanical
attachment of the EVAL-ADXL335Z to the application.
The dimensions of the EVAL-ADXL335Z are 20 mm × 20 mm
with mounting holes set 15 mm × 15 mm at the corners of the
printed circuit board (PCB).
CIRCUIT DESCRIPTION
The schematic of the EVAL-ADXL335Z is shown in Figure 1.
Analog bandwidth can be set by changing Capacitors C2, C3,
and C4. See the ADXL335 data sheet for a complete description
of the operation of the accelerometer.
The part layout of the EVAL-ADXL335Z is shown in Figure 2.
The EVAL-ADXL335Z has four factory installed 100 nF capa-
citors. C1 at V
S
is a bypass capacitor to reduce supply noise. C2,
C3, and C4 at X
OUT
, Y

, and Z
OUT
are filter capacitors to set the
bandwidth to 50 Hz (see Figure 1). Many applications require a
different bandwidth, in which case the user can change C2, C3,
and C4 as appropriate.
SPECIAL NOTES ON HANDLING
The EVAL-ADXL335Z is not reverse polarity protected.
Reversing the +V supply and ground pins can cause damage
to the ADXL335.
Dropping the EVAL-ADXL335Z on a hard surface can generate
several thousand gees (g) of acceleration, which may exceed the
data sheet absolute maximum limits. See the ADXL335 data
sheet for more information.
