The LIS3DH is an ultra low-power high performance three axes linear accelerometer belonging to the “nano” family, with digital I2C/SPI serial interface standard output. The device features ultra low-power operational modes that allow advanced power saving and smart embedded functions.

The LIS3DH has dynamically user selectable full scales of ±2g/±4g/±8g/±16g and it is capable of measuring accelerations with output data rates from 1 Hz to 5 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. 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. Thresholds and timing of interrupt generators are programmable by the end user on the fly. The LIS3DH has an integrated 32-level first in, first out (FIFO) buffer allowing the user to store data for host processor intervention reduction. The LIS3DH is available in small thin plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

lis3dh是一个超低功耗高性能的三轴线性加速度计属于“纳米”家庭，数字I2C/SPI串行接口标准输出。该设备具有超低功耗运行模式，让先进的省电和智能嵌入式功能。

lis3dh动态用户可选的全尺度的±2g／±4G /±8g /±16G，它能够测量加速度的输出数据率从1赫兹到5千赫。自检功能允许用户检查传感器在最终应用程序的功能。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。中断发生器的阈值和时间是可编程的终端用户的飞行。的lis3dh集成了一个32级的先入先出（FIFO）缓冲器允许用户存储数据的主机处理器干预减少。的lis3dh小薄塑料栅格阵列（LGA）封装，可它是保证工作在扩展的温度范围从- 40°C + 85°C.
