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
