Product overview

Description

The IIS3DHHC is an ultra-low noise, high-stability three-axis linear accelerometer. The IIS3DHHC 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 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.
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.
