Description
The MIS2DH is an ultra-low-power high-
performance three-axis linear accelerometer with
digital I²C/SPI serial interface standard output.
The MIS2DH has user-selectable full scales of
2g/±4g/8g/16g and is capable of measuring
accelerations with output data rates from 1 Hz to
5.3 kHz.
The MIS2DH is a device that has been conceived
for medical and healthcare applications whenever
the sensor itself is not used as a life-sustaining
component.
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 self-test capability allows the user to check
the functionality of the sensor in the final
application.
The MIS2DH 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.
