The STMicroelectronics IIS3DHHC is an ultra-low noise, high-stability, three-axis, linear accelerometer. It has a full scale of ±2.5 g and is capable of providing the measured accelerations through an SPI 4-wire digital interface. The sensing element is manufactured using a dedicated micromachining process. The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit, specifically trimmed to match the characteristics of the sensing element.
