The product measures acceleration 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 μg/√Hz, which allows signals below 2 mg to be resolved in tilt-sensing applications using narrow bandwidths (<60 Hz). The user selects the bandwidth of the accelerometer using capacitors CX and CY at the XOUT and YOUT pins. Bandwidths of 0.5 Hz to 2.5 k Hz can be selected to suit the application. The ADXL322 is available in a 4 mm × 4 mm × 1.45 mm, 16-lead, plastic LFCSP.
