Description

The LSM303DLH is a system-in-package

featuring a 3D digital linear acceleration sensor

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

is available in a plastic land grid array (LGA)

package, and is guaranteed to operate over an

extended temperature range from -30 to +85 °C.
