LSM303DLHC数字罗盘传感器

LSM303DLHC数字罗盘在单LGA封装内整合了1个三轴数字加速度计和1个三轴数字磁传感器。
 
意法半导体&rsquo的罗盘设计用于准确检测外部磁场的方向和强度，利用加速度计测量进行倾斜补偿，因此即使便携式器件发生倾斜也能保证非常准确的罗盘航向。
 
意法半导体&rsquo的低噪声电子罗盘具有2 mG的分辨率和很宽的满标范围，全都听凭用户选择：±2 ~ ±16g满标加速度和±1.3 ~ ±8G磁场满标。
 
罗盘系列产品具有嵌入式自测和智能电源功能，从而能够将电流消耗降至最低水平。

LSM303DLHC
Ultra compact high performance e-compass: 3D accelerometer and 3D magnetometer module
The LSM303DLHC is a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor.

LSM303DLHC has linear acceleration full-scales of ±2g / ±4g / ±8g / ±16g and a magnetic field full-scale of ±1.3 / ±1.9 / ±2.5 / ±4.0 / ±4.7 / ±5.6 / ±8.1 gauss. All full-scales available are fully able by the user.

LSM303DLHC includes an I2C serial bus interface that supports standard and fast mode 100 kHz and 400kHz. The system can be configured to generate interrupt signals 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. Magnetic and accelerometer parts can be enabled or put into power-down mode separately.

The LSM303DLHC is available in a plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range -40 °C to +85 °C.
