LIS1R02 Datasheet | STMicroelectronics

DESCRIPTION The LIS1R02 is a plete rotational accelerometer system based on a Σ∆ architecture, followed by a digital downsampling block and a digital filter, featuring high sensitivity, 800 Hz signal bandwidth and a plete serial port interface for a direct connection BLOCK DIAGRAM to microprocessor environment. An embedded PLL allows internal clock generation from an external synchronization signal. SENSOR A/D CONVERTER DIGITAL FILTER SER.
