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.
- Tire and battery pack monitoring
- High force event detection

Evaluation Kits (2)
The EVAL-ADXL314-SDP is an easy-to-use Customer Evaluation System that allows the user a quick start on testing an evaluating the ADXL314 accelerometer. The system consists of a main board (EVAL-SDP-CB1Z evaluation platform), an interface board (EVAL-SDP-INTERZ), and a satellite board (EVAL-ADXL314Z breakout board).
The EVAL-SDP-CB1Z board, also called “SDP-B”, connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The SDP-B is connected to the interface board (EVAL-SDP-INTERZ), which provides the signal conditioning and electrical connections to communicated with the satellite board (EVAL-ADXL314Z) through a cable. This cable allows the satellite to be easily manipulated for testing or separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components.
The main and interface boards are compatible with the EVAL-ADXL312Z and EVAL-ADXL313Z breakout boards as well.
The EVAL-ADXL314-SDP Customer Evaluation System comes with all the necessary cables and connectors. Each part of this kit can be purchased separately.
The EVAL-ADXL314Z is a simple evaluation board that allows quick evaluation of the performance of the ADXL314, 3-axis digital accelerometer. The EVAL-ADXL314Z is ideal for evaluation of the ADXL314 in an existing system because the stiffness and the small size of the EVAL-ADXL314Z minimizes the effect of the board on both the system and acceleration measurements.
For full details on the ADXL314, see the ADXL314 data sheet, which should be consulted in conjunction with the user guide when using the EVAL-ADXL314Z evaluation board.
Software & Systems Requirements
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
