DESCRIPTION
The EVAL-ADXL330Z is a simple evaluation board that allows
quick evaluation of the performance of the ADXL330 dual-axis
accelerometer. The EVAL-ADXL330Z has a 5-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-ADXL330Z to the application.
The EVAL-ADXL330Z is 20 mm × 20 mm with mounting holes
set 15 mm × 15 mm at the corners of the PCB.
CIRCUIT DESCRIPTION
The schematic of the EVAL-ADXL330Z is shown in Figure 1.
Analog bandwidth can be set by changing Capacitors C2, C3,
and C4. See the ADXL330 data sheet for a complete description
of the operation of the accelerometer.
The part layout of the EVAL-ADXL330Z is shown in Figure 2.
The EVAL-ADXL330Z has three factory installed 100 nF
capacitors (C2, C3, and C4) at XOUT, YOUT, and ZOUT to reduce
the bandwidth to 50 Hz. 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-ADXL330Z is not reverse polarity protected.
Reversing the +V supply and ground pins can cause damage to
the ADXL330.
Dropping the EVAL-ADXL330Z on a hard surface can generate
several thousand g of acceleration and might exceed the data
sheet absolute maximum limits. See the ADXL330 data sheet
for more information.
