The LIS3DHH is an ultra-high-resolution and low-noise three-axis linear accelerometer.
The LIS3DHH 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 LIS3DHH 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.
