3-Axis, ±1.5 g/±3 g/±6 g/±12 g
Digital Accelerometer
ADXL312 Data Sheet
FEATURES GENERAL DESCRIPTION Ultralow power: as low as 57 µA in measurement mode and
0.1 µA in standby mode at VS = 3.3 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 ±12 g (maintaining 2.9 mg/LSB
scale factor in all g ranges)
Embedded FIFO technology minimizes host processor load
Built-in motion detection functions for activity/inactivity
monitoring
Supply and I/O voltage range: 2.0 V to 3.6 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 to +105°C)
10,000 g shock survival
Pb free/RoHS compliant
Small and thin: 5 mm × 5 mm × 1.45 mm LFCSP package …
