LIS331DLH传感器变送器的运动传感器-加速计规格书PDF中文资料

LIS331DLH属于传感器变送器的运动传感器-加速计。由意法半导体集团制造生产的LIS331DLH运动传感器 - 加速计加速度计用于检测并响应运动或振动等加速度的变化。加速度计类型有 X、Y 或 Z 轴上的模拟或数字加速度计，加速度范围为 ±0.5 g 至 ±2000 g，灵敏度为 1 至 500 k (LSB/g)，输出类型有模拟电压、蓝牙、数字、DSI、IEPE、I2C、PCM、PWM、射频和 SPI。

Description

The LIS331DLH 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 sleep to wake-up functions.

The LIS331DLH has dynamically user selectable full scales of ±2g/±4g/±8g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 1 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 signal by 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 LIS331DLH 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.
