GENERAL DESCRIPTION
The ADXL314 is a ±200 g range, 13-bit resolution, 3-axis digital
accelerometer. The digital output data is formatted as 16-bit, twos
complement data and is accessible through a serial peripheral
interface (SPI), 3-wire or 4-wire, or an I2C digital interface.
An integrated memory management system with a 32 level, first in,
first out (FIFO) buffer can store data to minimize host processor
activity and lower overall system power consumption.
Low power modes enable intelligent motion-based power management
with threshold sensing and active acceleration measurement
at low power dissipation, typically 65 μA for VS = 2.5 V at a 100 Hz
output data rate (ODR).
The ADXL314 is supplied in a small, thin 5 mm × 5 mm × 1.45 mm,
32-lead LFCSP.
