ADXL322pdf (Small and Thin ±2

ADXL322是一款超小型封装(4 x 4 x 1.45 mm LFCSP)、低功耗（Vs = 2.4 V时为340 µA）± 2g iMEMS 加速度计，专为满足移动电话和其它便携式设备集成各种运动、倾斜和惯性检测特性（例如：数据输入、菜单和显示器控制、电源管理、态势感知、导航以及纵向与横向显示定位）的需求而设计。该器件还支持笔记本电脑中的硬盘驱动器保护系统和安全特性，以及鼠标和游戏杆设备等PC和游戏外设的位置与倾斜检测。

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.
