Description

The LSM303DLM is a system-in-package

featuring a 3D digital linear acceleration sensor

and a 3D digital magnetic sensor.

The various sensing elements are manufactured

by 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

LSM303DLM 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.

interface that supports standard mode (100 kHz)

and fast mode (400 kHz). 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 into power-down mode separately.

The LSM303DLM is available in a plastic land grid

array package (LGA), and is guaranteed to

operate over an extended temperature range from

-40 to +85 °C.
