ADXL344ACCZ-RL7

ADXL344 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. It measures acceleration with high resolution (13bit) measurement at upto ±16g. Digital output data is formatted as 16bit twos complement and is accessible through either a SPI (3- or 4-wire) or I²C digital interface. It 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°. It is used in applications such as handsets, gaming and pointing devices, hard disk drive (HDD) protection.
