This document provides application information for the LIS331DL low-voltage 3-axis digital output linear MEMS accelerometer. The accelerometer features ultra-compact size, low power consumption, and selectable ±2 g and ±8 g measurement ranges.
This document serves as an application note for the LIS331DL, an ultra-compact, low-power 3-axis linear MEMS accelerometer housed in an LGA package. It details the device's operation, including its sensing element and IC interface which provide acceleration data via an I2C/SPI serial interface. The note covers the device's capabilities, such as user-selectable full scales of +2 g and +8 g, output data rates of 100 Hz or 400 Hz, and features like self-test and programmable interrupt sources for inertial wake-up, free-fall detection, and click events.
