ADXL346ACCZ-R2

ADXL346ACCZ-R2 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) 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. It 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 (4mg/LSB) enables the 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. It is used in applications such as handsets, medical instrumentation, gaming and pointing devices, industrial instrumentation, personal navigation devices, hard disk drive (HDD) protection.

• Power consumption scales automatically with bandwidth, 2.6V specified voltage
• 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, 10,000g shock survival
• Supply and I/O voltage range from 1.7V to 2.75V, bandwidth selectable via serial command
• Flexible interrupt modes mappable to either interrupt pin
• Nonlinearity is ±0.5% typical at (TA = 25°C, VS = 2.6V, VDD I/O = 1.8V)
• Cross-axis sensitivity is ±1% typical at (TA = 25°C, VS = 2.6V, VDD I/O = 1.8V)
• Measurement mode supply current is 140μA typical at (ODR ≥ 100Hz, TA = 25°C)
• Operating temperature range from -40°C to +85°C, 16-terminal LGA package
