The 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 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 IIS3DHHC 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.
