Product Details","The ADXL343 is a versatile 3-axis, digital-output, low g MEMS accelerometer. Selectable measurement range and bandwidth, and configurable, built-in motion detection make it suitable for sensing acceleration in a wide variety of applications. Robustness to 10,000 g of shock and a wide temperature range (−40°C to +85°C) enable use of the accelerometer even in harsh environments.","The ADXL343 measures acceleration with high resolution (13-bit) measurement at up to ±16g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface. The ADXL343 can measure the static acceleration of gravity in tilt-sensing appli-cations, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg\/LSB) enables measurement of inclination changes less than 1.0°.","Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins.","An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption.","The ADXL343 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-terminal, plastic package.","Applications
