3 axis accelerometer-ADXL345



3 Axis Accelerometer – ADXL345:
The 3 Axis Accelerometer- ADXL345 is a small, thin and low power with high resolutions (13bit) measuring at up to +16 g. Digital output data is formatted as 16 bit twos complement and is accessible through either SPI(3- or40-wire) or I2C digital interface.



3 axis accelerometer-ADXL345 Features:

  • Ultralow power: as low as 40 μA in measurement mode and μA in standby mode at VS = 2.5 V (typical)
  • Power consumption scales automatically with bandwidth User-selectable resolution
  • Fixed 10-bit resolution
  • Full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g maintaining 4 mg/LSB scale factor in all g ranges)
  • Embedded, patent pending FIFO technology minimizes host processor load Tap/double tap detection
  • Activity/inactivity monitoring
  • Free-fall detection
  • Supply voltage range: 2.0 V to 3.6 V
  • I/O voltage range: 1.7 V to VS
  • SPI (3- and 4-wire) and I2C digital interfaces
  • Flexible interrupt modes mappable to either interrupt pin
  • Measurement ranges selectable via serial command
  • Bandwidth selectable via serial command
  • Wide temperature range (−40°C to +85°C)
  • 10,000 g shock survival
  • Pb free/RoHS compliant 
  • High quality PCB FR4 Grade with FPT Certified.
