ST IIS2DHTR

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 1Hz to 5.3kHz. 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℃ to +85℃.
