Overview
The LIS3DHHTR is an ultra-high-resolution and low-noise three-axis linear accelerometer produced by STMicroelectronics. This device is designed to provide precise measurements of acceleration in three axes, with a full scale of ±2.5 g. The accelerometer utilizes a dedicated micromachining process for the sensing element and a CMOS process for the IC interface, ensuring high integration and accuracy. It operates within an extended temperature range of -40 °C to +85 °C and is packaged in a high-performance (low-stress) ceramic cavity land grid array (CC LGA-16).
