描述 Description

The IIS2DH is an ultra-low-power high-performance three-axis linear accelerometer with digital I2C/SPI serial interface standard output.

The IIS2DH 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 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 IIS2DH 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.
