ADXL346ACCZ-RL7

ADXL346 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13bit) measurement at up to ±16g. Digital output data is formatted as 16bit twos complement and is accessible through either an SPI (3- or 4-wire) or I²C digital interface. This is well suited for mobile device 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 (4 mg/LSB) enables measurement of inclination changes of less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Application includes handsets, medical instrumentation, gaming and pointing devices, industrial instrumentation, personal navigation devices, hard disk drive (HDD) protection.

• ±2, ±4, ±8, ±16g measurement range, 2.6V specified voltage
• Ultralow power as low as 23μA in measurement mode and 0.2μA in standby mode at VS = 2.6V (typ)
• Power consumption scales automatically with bandwidth
• User-selectable resolution
• Fixed 10bit resolution
• Embedded memory management system with FIFO technology minimizes host processor load
• Single tap/double tap detection, activity/inactivity monitoring
• Free-fall detection, concurrent four- and six-position orientation detection
• Supply and I/O voltage range from 1.7V to 2.75V
• 16 terminal LGA package, operating temperature range from -40°C to +85°C
