Active production, digital MEMS accelerometer with embedded temperature sensor
The LIS2DTW12TR is an active-production MEMS digital accelerometer from STMicroelectronics, combining a three-axis (X, Y, Z) motion sensor with an on-chip temperature sensor in a single 12-WFLGA package.
Selectable acceleration range and bandwidth for motion sensing
The accelerometer offers four user-selectable full-scale ranges: ±2g, ±4g, ±8g, and ±16g, with corresponding sensitivity from 4098 LSB/g down to 512 LSB/g — the ±2g setting gives the finest resolution for tilt or vibration detection. Bandwidth is programmable from 0.8 Hz up to 800 Hz via the digital filter, letting you trade noise for response time depending on whether you are measuring slow orientation changes or higher-frequency impacts. The adjustable bandwidth and selectable scale are set through the I²C or SPI registers, so no external components are needed to reconfigure the sensor for different motion profiles.
