Data Sheet 3-Axis, ±2 g/±4 g/±8 g/±16 g
Digital MEMS Accelerometer
ADXL343 FEATURES GENERAL DESCRIPTION Multipurpose accelerometer with 10-to 13-bit resolution for
use in a wide variety of applications
Digital output accessible via SPI (3-and 4-wire) and I2C
Built-in motion detection features make tap, double-tap,
activity, inactivity, and free-fall detection trivial
User-adjustable thresholds
Interrupts independently mappable to two interrupt pins
Low power operation down to 23 µA and embedded FIFO for
reducing overall system power
Wide supply voltage range: 2.0 V to 3.6 V
I/O voltage 1.7 V to VS
Wide operating temperature range (−40°C to +85°C)
10,000 g shock survival
Small, thin, Pb free, RoHS compliant 3 mm × 5 mm × 1 mm
LGA package The ADXL343 is a versatile 3-axis, digital-output, low g MEMS
accelerometer. Selectable measurement range and bandwidth, and
configurable, built-in motion detection make it suitable for sensing
acceleration in a wide variety of applications. Robustness to
10,000 g of shock and a wide temperature range (−40°C to +85°C)
enable use of the accelerometer even in harsh environments.
The ADXL343 measures acceleration with high resolution (13-bit) …
