ADXL322是一款超小型封裝(4 x 4 x 1.45 mm LFCSP)、低功耗（Vs = 2.4 V時為340 μA）± 2g iMEMS 加速度計，專為滿足移動電話和其它便攜式設備集成各種運動、傾斜和慣性檢測特性（例如：數(shù)據(jù)輸入、菜單和顯示器控制、電源管理、態(tài)勢感知、導航以及縱向與橫向顯示定位）的需求而設計。該器件還支持筆記本電腦中的硬盤驅(qū)動器保護系統(tǒng)和安全特性，以及鼠標和游戲桿設備等PC和游戲外設的位置與傾斜檢測。

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 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 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.
