AN2847 Application note LIS331DLH: ±2 g /±4 g /±8 g digital output high performance ultra low-power 3-axis accelerometer
The document provides detailed application information for the LIS331DLH, a high-performance, ultra-low-power 3-axis linear MEMS accelerometer available in an LGA package. It covers key features such as dynamically user-selectable full scales of +2 g/+4 g/+8 g and output data rates ranging from 0.5 Hz to 1 kHz.
The guide details the start-up sequence, register configuration for various operating modes (Normal, Power Down, Low Power, Sleep to Wake), high-pass filter settings, and interrupt generation logic for free-fall, wake-up, and inertial events.
The LIS331DLH is a high performance ultra low-power 3-axis linear accelerometer.
The device has dynamically user-selectable full scales of +2 g, +4 g, and +8 g.
The device is guaranteed to operate over a wide temperature range of -40 °C to +85 °C.
