Description

The LIS331HH is an ultra low-power high

performance high full-scale three axes linear

accelerometer belonging to the “nano” family, with

The device features ultra low-power operational

modes that allow advanced power saving and

smart sleep to wake-up functions.

The LIS331HH has dynamically user selectable

full scales of ±6

g/±12g/±24g and it is capable of

measuring accelerations 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 contains 2 indipendent interrupt

engines able to recognize dedicated inertial

events.

Thresholds and timing of interrupt generators are

programmable by the end user on the fly.

The LIS331HH is available in small thin plastic

land grid array package (LGA) and it is

guaranteed to operate over an extended

temperature range from -40 °C to +85 °C.
