描述 Description

The LIS2DS12 is an ultra-low-power, high-performance three-axis linear accelerometer belonging to the “pico” family which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers.

The LIS2DS12 has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 6400 Hz.

The LIS2DS12 has an integrated 256-level first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor.

The embedded self-test capability allows the user to check the functioning of the sensor in the final application.

The LIS2DS12 has a dedicated internal engine architecture in order to process internally motion and acceleration detection including free-fall, wakeup, single and double-tap detection, activity-inactivity, portrait and landscape detection, step counter and step detection along with significant motion detection.

The LIS2DS12 is available in a small thin plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
