LIS2DH12 MEMS digital output motion sensor: ultra-low-power high-performance 3-axisfemt accelerometer Datasheet - production data Description The LIS2DH12 is an ultra-low-power high- performance three-axis linear accelerometer 2 belonging to the femto family with digital I C/SPI serial interface standard output. /* PP The LIS2DH12 has user-selectable full scales of 2g/4g/8g/16g and is capable of measuring accelerations with output data rates from 1 Hz to Features 5.3 kHz. The self-test capability allows the user to check Wide supply voltage, 1.71 V to 3.6 V the functionality of the sensor in the final Independent IO supply (1.8 V) and supply application. voltage compatible The device may be configured to generate Ultra-low power consumption down to 2 A interrupt signals by detecting two independent 2g/4g/8g/16g selectable full scales inertial wake-up/free-fall events as well as by the 2 position of the device itself. I C/SPI digital output interface 2 independent programmable interrupt The LIS2DH12 is available in a small thin plastic generators for free-fall and motion detection land grid array package (LGA) and is guaranteed to operate over an extended temperature range 6D/4D orientation detection from -40 C to +85 C.
