Description
The LIS3DHH is an ultra-high-resolution and lownoise
three-axis linear accelerometer.
The LIS3DHH has a full scale of 2.5 g and is
capable of providing the measured accelerations
to the application through an SPI 4-wire digital
interface.
The sensing element is manufactured using a
dedicated micromachining process developed by
STMicroelectronics to produce inertial sensors
and actuators on silicon wafers.
The IC interface is manufactured using a CMOS
process that allows a high level of integration to
design a dedicated circuit which is trimmed to
better match the characteristics of the sensing
element.
The LIS3DHH is available in a high-performance
(low-stress) ceramic cavity land grid array (CC
LGA) package and can operate within a
temperature range of -40 °C to +85 °C.

Applications
 Precision inclinometer
 Platform and antenna stabilization
 Leveling instruments
