3-Axis, ±2 g/±4 g/±8 g/±16 g
Ultralow Power Digital Accelerometer
ADXL346 Data Sheet
FEATURES GENERAL DESCRIPTION Ultralow power: as low as 23 μA in measurement mode and
0.2 μA in standby mode at VS = 2.6 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 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: 1.7 V to 2.75 V
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) …
