ADXL325
GENERAL DESCRIPTION
The ADXL325 is a small, low power, complete 3-axis accelerometer
with signal conditioned voltage outputs. The product measures
acceleration with a minimum full-scale range of ±5 g. It can
measure the static acceleration of gravity in tilt-sensing applications,
as well as dynamic acceleration, resulting from motion, shock,
or vibration.
The user selects the bandwidth of the accelerometer using
the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
Bandwidths can be selected to suit the application with a range
of 0.5 Hz to 1600 Hz for X and Y axes and a range of 0.5 Hz to
550 Hz for the Z axis.
The ADXL325 is available in a small, low profile, 4 mm ×
4 mm × 1.45 mm, 16-lead, plastic lead frame chip scale package
(LFCSP_LQ).
