Overview
The LIS3L02DQ is a three-axis digital output linear accelerometer produced by STMicroelectronics. It integrates a sensing element and an IC interface, enabling the measurement of acceleration signals along three axes. The device is manufactured using a dedicated process for inertial sensors and a CMOS process for the IC interface, ensuring high integration and factory-calibrated performance. It operates within a temperature range of -20°C to +70°C and is available in a plastic SMD package.
