高性能ADXL350是一款小尺寸薄型低功耗3轴加速度计，具有高分辨率（13位）和高达±8 g的可选测量范围。ADXL350提供业界领先的温度性能，保证了温度范围内的最低/最高失调规格。数字输出数据为16位二进制补码格式，可通过SPI（3线或4线）或者I2C 数字接口访问。

ADXL350非常适合高性能便携式应用。它可以在倾斜检测应用中测量静态重力加速度，还可以测量运动或冲击导致的动态加速度。它具有高分辨率(2 mg/LSB)，能够分辨不到1.0°的倾斜度变化。

该器件提供多种特殊检测功能。活动和非活动检测功能检测有无运动发生，以及任意轴上的加速度是否超过用户设置的限值。敲击检测功能可以检测单击和双击动作。自由落体检测功能可以检测器件是否正在掉落。这些功能可以映射到两个中断输出引脚中的一个。

低功耗模式支持基于运动的智能电源管理，从而以极低的功耗进行阈值感测和运动加速度测量。

ADXL350采用3 mm × 4 mm × 1.2 mm、16引脚小型空腔层压封装。

应用

The iMEMS®ADXL350 inertial sensor evaluation systemis an easy-to-use evaluation tool targeting bench or desktop characterization of Analog Devices, Inc., inertial sensor products. The system consists of the inertial sensor evaluation board (ISEB), or main board, and a satellite board for any Analog Devices inertial sensor product. The ISEB connects directly to a PC via an USB cable, with the USB connection providing both power and communications to the board. The ISEB is connected to the satellite board through a ribbon cable. This cable allows the satellite to be easily manipulated for testing or separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components.The ISEB is a universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated.

The EVAL-ADXL350Z is a simple breakout board that enables easy connection of anADXL350 into an existing system.Due to its small size, the EVAL-ADXL350Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL350 in an existing system. Note that the ADXL350 must be communicated with digitally via SPI or I2C. No processor is included with the EVAL-ADXL350Z; firmware must be supplied externally by the user. For evaluation boards that include a processor, please see the EVAL-ADXL350Z-M and EVAL-ADXL350Z-S
