Description：

The LIS2DTW12 is an ultralow-power high-performance three-axis linear accelerometer and temperature sensor belonging to the “femto” family, which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers.The device has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1.6 Hz to 1600 Hz.

The LIS2DTW12 has an embedded 0.8 °C (typ. accuracy) temperature sensor with ODRs ranging from 50 to 1.6 Hz and resolution from 8 to 12 bits. The LIS2DTW12 has an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor.
