serial interface standard output. The device
features ultra low-power operational modes that
allow advanced power saving and smart
embedded functions.
The LIS3DH has dynamically user selectable full
scales of
±2g/±4g/±8g/±16g
and it is capable of
measuring accelerations with output data rates
from 1 Hz to 5 kHz. The self-test capability allows
the user to check the functioning of the sensor in
the final application. The device may be
configured to generate interrupt signals by two
independent inertial wake-up/free-fall events as
well as by the position of the device itself.
Thresholds and timing of interrupt generators are
programmable by the end user on the fly. The
LIS3DH has an integrated 32-level first in, first out
(FIFO) buffer allowing the user to store data for
host processor intervention reduction. The
LIS3DH is available in small thin plastic land grid
array package (LGA) and it is guaranteed to
operate over an extended temperature range from
-40 °C to +85 °C.
