GENERAL DESCRIPTION
The ADXL322 is a small, thin, low power, complete, dual-axis
accelerometer with signal conditioned voltage outputs, which
are all on a single monolithic IC. The product measures accel-
eration with a full-scale range of ±2
g
(typical). It can also
measure both dynamic acceleration (vibration) and static
acceleration (gravity).
The ADXL322’s typical noise floor is 220 μ
g
/√Hz, which allows
signals below 2 m
g
to be resolved in tilt-sensing applications
using narrow bandwidths (<60 Hz).
The user selects the bandwidth of the accelerometer using
capacitors C
X
and C
Y
at the X
OUT
and Y
OUT
pins. Bandwidths
of 0.5 Hz to 2.5 kHz can be selected to suit the application.
The ADXL322 is available in a 4 mm × 4 mm × 1.45 mm,
16-lead, plastic LFCSP.
