Description
The LIS352AX is a new small size, low-power 3-
axis linear accelerometer that includes a sensing
element and an IC interface capable of providing
an absolute analog signal to the external world.
The IC interface is manufactured using a CMOS
process that allows a high level of integration to
design a dedicated circuit trimmed to better match
the sensing element characteristics.
LGA-14 (3x5x0.9mm)
The LIS352AX 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 system.
An embedded multiplexer allows the 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 LIS352AX is provided in a plastic land grid
array (LGA) package.
Several years ago ST successfully pioneered the
use 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.
