Overview
The LIS302DLH is an ultra low-power, high-performance three-axis linear accelerometer produced by STMicroelectronics. It belongs to the 'piccolo' family and features a digital I2C/SPI serial interface. This accelerometer is designed for advanced power saving and includes smart sleep to wake-up functions. The device is capable of measuring accelerations with dynamically user-selectable full scales of ±2g, ±4g, and ±8g, and it supports output data rates from 0.5 Hz to 1 kHz. The LIS302DLH is packaged in a small, thin plastic Land Grid Array (LGA) and operates over an extended temperature range from -40°C to +85°C.
