Product Details

The ADXL313 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ±4g. Digital output data is formatted as 16-bit twos complement and is accessible through either a serial port interface (SPI) (3-wire or 4-wire) or I2C digital interface.

The ADXL313 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 (1024 LSB/g) and low noise (150 μg/√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.

Several built-in sensing functions are provided. Activity and inactivity sensing detects the presence or absence of motion and whether the acceleration on any axis exceeds a user-set level. These functions can be mapped to interrupt output pins. An integrated 32-level FIFO can be used to store data to minimize host processor intervention, resulting in reduced system power consumption.

Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

The ADXL313 is supplied in a small, thin 5 mm × 5 mm × 1.45 mm, 32-lead LFCSP package and is pin compatible with the ADXL312 accelerometer device.
