LIS2DTW12 – TEMPERATURE SENSOR COMBINED WITH A 3-AXIS MEMS ACCELEROMETER

The LIS2DTW12 is an ultra-low-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.

LIS2DTW12 – TEMPERATURE SENSOR COMBINED WITH A 3-AXIS MEMS ACCELEROMETER

  • 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.
  • The embedded self-test capability allows the user to check the functioning of the sensor in the final application.
  • The device has a dedicated internal engine to process motion and acceleration detection including free-fall, wakeup, highly configurable single/double-tap recognition, activity/inactivity, stationary/motion detection, portrait/landscape detection and 6D/4D orientation.
  • The LIS2DTW12 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.
