Product Overview

The ADXL343BCCZ is a versatile 3-axis Digital MEMS Accelerometer suitable for sensing acceleration in a wide variety of applications. It measures acceleration with high resolution (13-bit) measurement at up to ±16 g. 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 applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9mg/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.
  • Multipurpose accelerometer with 10 to 13-bit resolution for use in a wide variety of applications
  • Digital output accessible via SPI (3 and 4-wire) and I²C
  • User-adjustable thresholds
  • Interrupts independently mappable to two interrupt pins
  • Low power operation down to 23µA and embedded FIFO for reducing overall system power
  • 10,000g Shock survival
ESD sensitive device, take proper precaution while handling the device.
