LIS2DE12中文资料3轴MEMS加速度计，超低功耗2 µA，±2g/±4g/±8g/±16g满量程，高速I2C/SPI数字输出，内置FIFO和高性能加速度传感器，VFLGA封装数据手册ST规格书

描述 Description

The LIS2DE12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family with digital I2C/SPI serial interface standard output.

The LIS2DE12 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 self-test capability allows the user to check the functionality of the sensor in the final application.

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

The LIS2DE12 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.
