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.APPLICATIONSCar alarmsHill start aid (HSA) systemsElectronic parking brakesData recorders (black boxes)

The ADXL314 is a ±200grange, 13-bit resolution, 3-axis digital accelerometer. The digital output data is formatted as 16-bit, twos complement data and is accessible through a serial peripheral interface (SPI), 3-wire or 4-wire, or an I2C digital interface.An integrated memory management system with a 32 level, first in, first out (FIFO) buffer can store data to minimize host processor activity and lower overall system power consumption.Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at low power dissipation, typically 65 μA for VS= 2.5 V at a 100 Hz output data rate (ODR).The ADXL314 is supplied in a small, thin 5 mm × 5 mm × 1.45 mm, 32-lead LFCSP.APPLICATIONSTire and battery pack monitoringHigh force event detection
