Description

The LIS352AR is a miniaturized low-power 3-axis

linear accelerometer belonging to the “piccolo”

family of ST motion sensors. It includes a sensing

element and an IC interface to provide an analog

signal to the external world.

The sensing element, capable of detecting the

acceleration, is manufactured using a dedicated

process developed by ST to produce motion

sensors and actuators in silicon.

The IC interface is manufactured using a CMOS

process that allows the design of a dedicated

circuit which is trimmed to better match the

sensing element characteristics.

The LIS352AR has a full-scale of ±2

g and is

capable of measuring accelerations over a

maximum bandwidth of 2.0 kHz. The device

bandwidth may be reduced by using external

capacitors. The self-test capability allows the user

to check the functioning of the sensor in the final

application.

The device has three analog acceleration outputs,

plus an embedded multiplexer that allows for

redirection of the analog outputs onto a single pin

for operation with a single-channel A/D converter.

ST is already in the field with several hundred

million sensors which have received excellent

acceptance from the market in terms of quality,

reliability and performance

The LIS352AR is provided in a plastic land grid

array (LGA) package.

Several years ago ST successfully pioneered the

usage of this package for accelerometers. Today,

ST has the widest manufacturing capability and

strongest expertise in the world for production of

sensors in plastic LGA packages.
