ADXL350

Data Sheet FEATURES Excellent zero-g bias accuracy and stability with minimum/maximum specifications Ultralow power: as low as 45 μA in measurement mode and 0.1 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 ±8 g (maintains 2 mg/LSB scale factor in all g ranges) Embedded, 32-level FIFO buffer minimizes host processor load Tap/double tap detection and free-fall detection Activity/inactivity monitoring 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 Small and thin: 4 mm × 3 mm × 1.2 mm cavity LGA package 3-Axis, ±1g/±2g/±4g/±8g Digital Accelerometer ADXL350 GENERAL DESCRIPTION The high performance ADXL350 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) and selectable measurement ranges up to ±8 g. The ADXL350 offers industryleading noise and temperature performance for application robustness with minimal calibration. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL350 is...
