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.
