Description：

The IIS2DH is an ultra-low-power highperformance three-axis linear accelerometer withdigital I2C/SPI serial interface standard output.The IIS2DH has user-selectable full scales of2g/±4g/8g/16g and is capable of measuringaccelerations with output data rates from 1 Hz to5.3 kHz.The device may be configured to generateinterrupt signals by two independent inertialwake-up/free-fall events as well as by the positionof the device itself.The self-test capability allows the user to checkthe functionality of the sensor in the finalapplication.The IIS2DH is available in a small thin plastic landgrid array package (LGA) and is guaranteed tooperate over an extended temperature rangefrom -40 °C to +85 °C.
