Digital Accelerometer
ADXL345 FEATURES GENERAL DESCRIPTION Ultralow power: as low as 23 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 ±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
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 …

Small and thin: 3 mm × 5 mm × 1 mm LGA package The ADXL345-EP is an extended performance version of
the ADXL345, which is a small, thin, ultralow power, 3-axis
accelerometer with high resolution (13-bit) measurement at up to
±16 g. Digital output data is formatted as 16-bit twos complement
and is accessible through either a SPI (3-or 4-wire) or I2C digital …
