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.
