Description
The LIS2DH12 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 LIS2DH12 has 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 functionality 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 LIS2DH12 is available in a small thin plastic
land grid array package (LGA) and is guaranteed
to operate over an extended temperature range
from -40 °C to +85 °C.
