Analog Devices Inc. ADXL314 ±200g 3-Axis Digital Accelerometer

Analog Devices Inc. ADXL314 ±200g 3-Axis Digital Accelerometer outputs digital data formatted as 16-bit, twos complement and is accessible via a serial peripheral interface (SPI), 3-wire or 4-wire, or an I2C digital interface. The device implements an integrated memory management system with a 32-level, first in, first out (FIFO) buffer able to store data minimizing host processor activity and lower overall system power consumption. The low power modes of the ADI ADXL314 accelerometer allow intelligent motion-based power management with threshold sensing and active acceleration measurement at low power dissipation, typically 65μA for VS = 2.5V at a 100Hz output data rate (ODR). The ADXL314 is encapsulated in a small, thin 5mm × 5mm × 1.45 mm, 32-lead LFCSP.
