STMicroelectronics LIS2DUXS12 Ultra Low-Power Accelerometer
STMicroelectronics LIS2DUXS12 Ultra Low-Power Accelerometer is a smart, digital, 3-axis linear accelerometer. The STMicroelectronics LIS2DUXS12 MEMS and ASIC are designed to combine the lowest current consumption possible with features like always-on anti-aliasing filtering and a finite state machine (FSM). Features also include a machine learning core (MLC) with adaptive self-configuration (ASC) and an analog hub / Qvar sensing channel.Features
