IIS3DHHCTR

IIS3DHHCTR is a IIS3DHHC high-resolution, high-stability 3-axis digital linear accelerometer. It has a full scale of ±2.5g 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. Typical applications are precision inclinometer, antenna and platform pointing and levelling, levelling instruments.
