LIS331DLH: ±2 g /±4 g /±8 g digital output
high performance ultra low-power 3-axis accelerometer
Introduction
This document provides application information for the low-voltage 3-axis digital output
linear MEMS accelerometer provided in the LGA package.
The LIS331DLH is a high performance ultra low-power 3-axis linear accelerometer, which
belongs to the “nano” family of MEMS accelerometers, with digital I²C/SPI serial interface
standard output.
The device features ultra low-power operational modes that allow advanced power saving
and smart Sleep to Wakeup functions.
The LIS331DLH has dynamically user-selectable full scales of ±2 g /±4 g /±8 g and is
capable of measuring acceleration with output data rates from 0.5 Hz to 1 kHz.
The self-test capability allows the user to check the functioning of the sensor in the final
application.
The device can be configured to generate interrupt signals in response to inertial wake-
up/free-fall events, or based on the position of the device itself.
The thresholds and timing of interrupt generators are programmable by the end user while
fully operational. The LIS331DLH is available in a small, thin plastic land grid array (LGA)
package, and is guaranteed to operate over a wide temperature range of -40 °C to +85 °C.
