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.

1. Typical specifications are not guaranteed.
2. Verified by wafer level test and measurement of initial offset and sensitivity.
3. Typical zero-g level offset value after MSL3 preconditioning.
4. Offset can be eliminated by enabling the built-in high pass filter.
5. The sign of “Self-test output change” is defined by CTRL_REG4 ST bit, for all axes.
6. “Self-test output change” is defined as the absolute value of:
OUTPUT[LSb](Self test enabled) - OUTPUT[LSb](Self test disabled). 1LSb=4mg at 10bit representation, ±2 g Full-scale
7. After enabling ST, correct data is obtained after two samples (Low power mode / Normal mode) or after eight samples (high
resolution mode).
