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,
±5 g, or ±18 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 CX and Capacitor CY at the XOUT and YOUT pins.
Bandwidths of 0.5 Hz to 2.5 kHz can be selected to suit the
application.
The ADXL103 and ADXL203 are available in a 5 mm × 5 mm ×
2 mm, 8-terminal ceramic LCC package.
