LSM303DLHC Ultra-compact high-performance eCompass module: 3D accelerometer and 3D magnetometer Datasheet - production data Display orientation Gaming and virtual reality input devices Impact recognition and logging Vibration monitoring and compensation Description LGA-14 (3x5x1mm) The LSM303DLHC is a system-in-package featuring a 3D digital linear acceleration sensor Features and a 3D digital magnetic sensor. 3 magnetic field channels and 3 acceleration The LSM303DLHC has linear acceleration full channels scales of 2g / 4g / 8g / 16g and a magnetic field full scale of 1.3 / 1.9 / 2.5 / 4.0 / 4.7 / From 1.3 to 8.1 gauss magnetic field full 5.6 / 8.1 gauss. scale 2 The LSM303DLHC includes an I C serial bus 2g/4g/8g/16g linear acceleration full scale interface that supports standard and fast mode 16-bit data output 100 kHz and 400 kHz. The system can be 2 I C serial interface configured to generate interrupt signals by inertial wake-up/free-fall events as well as by the position Analog supply voltage 2.16 V to 3.6 V of the device itself. Thresholds and timing of Power-down mode / low-power mode interrupt generators are programmable by the end 2 independent programmable interrupt user. Magnetic and accelerometer blocks can be generators for free-fall and motion detection enabled or put into power-down mode separately. Embedded temperature sensor The LSM303DLHC is available in a plastic land Embedded FIFO grid array package (LGA) and is guaranteed to operate over an extended temperature range 6D/4D-orientation detection from -40 C to +85 C.
