Description

The LIS35DE is an ultra compact low-power three

axis linear accelerometer. It includes a sensing

element and an IC interface able to provide the

measured acceleration to the external world

through I

2C/SPI serial interface.

The sensing element, capable of detecting the

acceleration, is manufactured using a dedicated

process developed by ST to produce inertial

sensors and actuators in silicon.

The IC interface is manufactured using a CMOS

process that allows to design a dedicated circuit

which is trimmed to better match the sensing

element characteristics.

The LIS35DE has dynamically user selectable full

scales of ±2g/±8g and it is capable of measuring

accelerations with an output data rate of 100 Hz

or 400 Hz.

The device may be configured to generate inertial

wake-up/free-fall interrupt signals when a

programmable acceleration threshold is crossed

at least in one of the three axes. Thresholds and

timing of interrupt generators are programmable

by the end user on the fly.

The LIS35DE is available in plastic ThinLand

Grid Array package (TGA) and it is designed to

operate over an extended temperature range from

-40°C to +85°C.
