Accelerometer
ADXL337
GENERAL DESCRIPTION
The ADXL337 is a small, thin, low power, complete 3-axis
accelerometer with signal conditioned voltage outputs. The
product measures acceleration with a minimum full-scale range
of ±3 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 ADXL337 is available in a small, low profile, 3 mm × 3 mm ×
1.45 mm, 16-lead, lead frame chip scale package (LFCSP_LQ).
