Description
The LIS2DH is an ultra low-power high
performance three-axis linear accelerometer
belonging to the “femto” family, with digital I²C/SPI
serial interface standard output.
The LIS2DH 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 5.3 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.
The LIS2DH is available in small thin plastic land
grid array package (LGA) and is guaranteed to
operate over an extended temperature range from
-40 °C to +85 °C.
