The LIS35DE is an ultra compact low-power three axis linear accelerometer. It includes a sensing element and an IC interface able to provide the measured acceleration to the external world through I²C/SPI serial interface.

The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon.

The IC interface is manufactured using a CMOS process that allows to design a dedicated circuit which is trimmed to better match the sensing element characteristics.

The LIS35DE has dynamically user selectable full scales of ±2g/±8g and it is capable of measuring accelerations with an output data rate of 100 Hz or 400 Hz.

The device may be configured to generate inertial wake-up/free-fall interrupt signals when a programmable acceleration threshold is crossed at least in one of the three axes. Thresholds and timing of interrupt generators are programmable by the end user on the fly.

The LIS35DE is available in plastic Thin Land Grid Array package (TGA) and it is designed to operate over an extended temperature range from -40°C to +85°C.

这是一种超小型低功耗lis35de三轴线性加速度计。它包括一个传感元件和一个集成电路接口能够通过I2C和SPI串行接口到外部世界提供的加速度测量。

的传感元件，能够检测的加速度，使用一个专门的过程开发的由圣生产的惯性传感器和致动器在硅中使用。

IC接口是使用CMOS工艺，可以设计一个专门的电路，修整，以更好地匹配传感元件特性制造。

具有用户可选的lis35de动态全尺度的±2g／±8G，它能够以100赫兹或400赫兹的输出数据速率测量加速度。

该装置可配置为产生惯性唤醒/自由落下的中断信号，当可编程的加速度阈值交叉至少在三个轴之一。中断发生器的阈值和时间是可编程的终端用户的飞行。
