Description
The LSM303DLHC is a system-in-package
featuring a 3D digital linear acceleration sensor
and a 3D digital magnetic sensor.
The 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.
The LSM303DLHC includes an I2C serial bus
interface that supports standard and fast mode
100 kHz and 400 kHz. 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. Magnetic and accelerometer blocks 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
from -40 °C to +85 °C.
