LIS2DTW12 Sensor IC MEMS Digital Output Dual Motion And Temperature Sensor with Ultralow Power Consumption and ±2g/±4g/±8g/±16g Full Scale

LIS2DTW12 is an ultralow-power high-performance three-axis linear accelerometer and temperature sensor belonging to the "femto" family, leveraging robust and mature manufacturing processes used for micromachined accelerometers.

The sensor features user-selectable full scales of ±2g/±4g/±8g/±16g and measures accelerations with output data rates from 1.6 Hz to 1600 Hz. It includes an embedded temperature sensor with 0.8°C typical accuracy, ODRs from 50 to 1.6 Hz, and resolution from 8 to 12 bits.

An integrated 32-level first-in, first-out (FIFO) buffer allows data storage to limit host processor intervention.
