STMicroelectronics LIS2D MEMS-Bewegungssensor mit Digitalausgang
Der LIS2D MEMS-Bewegungssensor mit Digitalausgang von STMicroelectronics ist ein Hochleistungs-Beschleunigungsmesser mit drei Achsen und Teil der "femto" Produktfamilie mit serieller, digitaler I2C/SPI-Schnittstelle mit Standardausgabe. Er hat vom Anwender dynamisch wählbare Vollskalenbereiche von ±2g/±4g/±8g/±16g und misst Beschleunigungen mit Ausgangsdatenraten von 1 Hz bis 5,3 kHz. Außerdem kann der LIS2D so eingestellt werden, dass er Interrupt-Signale durch zwei unabhängige Wake-up/Free-fall-Trägheitsereignisse oder die Position des Bauelements generiert.
The LIS2DW12 is an ultra-low power three-axis linear accelerometer showing the best trade-off between resolution versus power consumption. The device is able to work in multi operation mode with up to 14 bit resolution and down to 0.38µA as a perfect choice for extreme low power applications such as wearable.
The LIS2DH12 three-axis linear accelerometer features up to 12 bit resolution, provides high performance and embedded functionalities without sacrificing the power consumption. The LIS2DE12 is the STMicroelectronics entry level accelerometer with 8 bit resolution suitable for applications requiring low power and cost effective solutions. The LIS2DS12 is an ultra-low-power, high-performance three-axis linear accelerometer belonging to the “pico” family which leverages on the robust and mature manufacturing processes already used for the production of micro-machined accelerometers.
