GENERAL DESCRIPTION
The ADXL103/ADXL203 are high precision, low power,
complete single and dual axis accelerometers with signal
conditioned voltage outputs, all on a single monolithic IC. The
ADXL103/ADXL203 measures acceleration with a full-scale
range of ±1.7
g
. The ADXL103/ADXL203 can measure both
dynamic acceleration (e.g., vibration) and static acceleration
(e.g., gravity).
The typical noise floor is 110 μ
g
/√Hz, allowing signals below
1 m
g
(0.06° of inclination) 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 may be selected to suit the application.
The ADXL103 and ADXL203 are available in 5 mm × 5 mm ×
2 mm, 8-pad hermetic LCC packages.
