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 measure acceleration with a full-scale
range of ±1.7 g. The ADXL103/ADXL203 can measure both
dynamic acceleration (for example, vibration) and static
acceleration (for example, gravity).
The typical noise floor is 110 μg/√Hz, allowing signals below
1 mg (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
Capacitor C
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.
