Overview
The LIS3DH is an ultra-low-power, high-performance three-axis linear accelerometer produced by STMicroelectronics. It belongs to the 'nano' family and features a digital I2C/SPI serial interface for output. The device is designed for advanced power saving and includes smart embedded functions. It is capable of measuring accelerations with dynamically user-selectable full scales of ±2g, ±4g, ±8g, and ±16g, and output data rates ranging from 1 Hz to 5.3 kHz. The LIS3DH also includes a self-test capability and can generate interrupt signals based on inertial wake-up/free-fall events and device position. It operates over an extended temperature range from -40 °C to +85 °C and is available in a small thin plastic land grid array (LGA) package.
