ANALOG DEVICES ADXL313WACPZ-RL

ADXL313 is a small, thin, low power, 3-axis accelerometer with high resolution (13bit) measurement upto ±4g. Digital output data is formatted as 16bit twos complement and is accessible through either a serial port interface (SPI) (3-wire or 4-wire) or I²C digital interface. It is well suited for car alarm or black box applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (1024LSB/g) and low noise (150µg/√Hz) enable resolution of inclination changes of as little as 0.1°. A built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.025° of inclination. It is used in applications such as car alarms, hill start aid (HSA) systems, electronic parking brakes, data recorders (black boxes).
