Overview
The LIS331DLH 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. This device is designed for advanced power saving with ultra-low-power operational modes and smart sleep-to-wake-up functions. It is capable of measuring accelerations with dynamically selectable full scales of ±2g/±4g/±8g and output data rates from 0.5 Hz to 1 kHz. The LIS331DLH is available in a small thin plastic land grid array (LGA) package and operates over an extended temperature range from -40°C to +85°C.
