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 g/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 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.
