LSM303DLHC LSM303DLH LEM303DLM數字羅盤在單LGA封裝內整合瞭1個三軸數字加速度計和1個三軸數字磁傳感器。
 
意法半導體&rsquo的羅盤設計用於準確檢測外部磁場的方向和強度，利用加速度計測量進行傾斜補償，因此即使便攜式器件發生傾斜也能保證非常準確的羅盤航向。
 
意法半導體&rsquo的低噪聲電子羅盤具有2 mG的分辨率和很寬的滿標范圍，全都聽憑用戶選擇：±2 ~ ±16g滿標加速度和±1.3 ~ ±8G磁場滿標。
 
羅盤系列產品具有嵌入式自測和智能電源功能，從而能夠將電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.
