The IIS2DH is an ultra-low-power high-performance three-axis linear accelerometer with digital I²C/SPI serial interface standard output.

The IIS2DH has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz.

The device may be configured to generate interrupt signals by two independent inertial wake-up/free-fall events as well as by the position of the device itself.

The self-test capability allows the user to check the functionality of the sensor in the final application.

The IIS2DH is available in a small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

iis2dh是一个超低功耗高性能轴线性加速度计的数字I2C和SPI串行接口标准输出。

iis2dh具有用户可选的全尺度的±2g／±4G /±8g /±16G和能够测量加速度的输出数据速率从1赫兹到5.3千赫。

该设备可以配置为产生中断信号由2个独立的惯性唤醒/自由坠落事件，以及由该设备本身的位置。

自检功能允许用户在最后的应用程序中检查传感器的功能。

在一个小的iis2dh薄塑料栅格阵列（LGA）封装提供并保证工作在扩展温度范围从- 40°C + 85°C.
