Description

The IIS2ICLX is a high-accuracy (ultralow noise, high stability, and repeatability) and

low-power, two-axis linear accelerometer with digital output.

The IIS2ICLX has a selectable full scale of ±0.5/±1/±2/±3 g and is capable of

providing the measured accelerations to the application over an I²C or SPI digital

interface.

Its high accuracy, stability over temperature, and repeatability make IIS2ICLX

particularly suitable for inclination measurement applications (inclinometers).

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.
