GENERAL DESCRIPTION

The ADXL346 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 an SPI (3- or 4-wire) or I2C? digital interface.

FEATURES

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)

Patent pending, 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)

10,000 g shock survival

Pb free/RoHS compliant

Small and thin: 3 mm × 3 mm × 0.95 mm LGA package
