Accelerometer
ADXL327
GENERAL DESCRIPTION
The ADXL327 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 ±2 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 ADXL327 is available in a small, low profile, 4 mm ×
4 mm × 1.45 mm, 16-lead, plastic lead frame chip scale package
(LFCSP_LQ).
