LGA-28L (5x5x1.0 mm)
and a 3D digital magnetic sensor. The various
sensing elements are manufactured using
specialized micromachining processes, while the
IC interfaces are realized using a CMOS
technology that allows the design of a dedicated
circuit which is trimmed to better match the
sensing element characteristics. The
LSM303DLH has a linear acceleration full-scale
of ±2 g / ±4 g / ±8 g and a magnetic field full-scale
of ±1.3 / ±1.9 / ±2.5 / ±4.0 / ±4.7 / ±5,6 / ±8.1
gauss, both fully selectable by the user. The
LSM303DLH includes an I²C serial bus interface
that supports standard mode (100 kHz) and fast
mode (400 kHz). The internal self-test capability
allows the user to check the functioning of the
whole module in the final application. The system
can be configured to generate an interrupt signal
by inertial wakeup/free-fall events, as well as by
the position of the device itself. Thresholds and
timing of interrupt generators are programmable
on the fly by the end user. Magnetic and
accelerometer parts can be enabled or put in
power-down mode separately. The LSM303DLH
