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
LGA-14 (3x5x0.9mm)
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.
