The ADXL380 is a low noise density, low power, 3-axis accelerometer with selectable measurement ranges. The ADXL380 supports the ±4 g, ±8 g, and ±16 g ranges.
The ADXL380 offers industry leading noise, enabling precision applications with minimal calibration. The low noise and low power ADXL380 enables accurate measurements of audio signals or heart sounds even in high vibration environments.
The ADXL380 multifunction pin names may be referenced only by their relevant function for either the serial peripheral interface (SPI) or inter-IC(I2C) interface, or these pin names can be referenced by their audio function (pulse density modulation (PDM), inter-IC sound (I2S), or time division multiplexing (TDM)).
In addition to its low power consumption, the ADXL380 has many features to enable true system level performance. These features include a built-in micropower temperature sensor, singletap, double tap, and triple tap detection, and a state machine to prevent false triggering. In addition, the ADXL380 has provisions for external control of the sampling time and/or an external clock.
The ADXL380 operates on a wide, 2.25 V to 3.6 V supply range (or 1.8 V supply) and can interface, if necessary, to a host operating on a separate supply voltage. The ADXL380 is available in a 14-terminal, 2.9 mm × 2.8 mm × 0.87 mm, LGA package.

EVAL-ADIS-MCBZ User Guide
Product Detail
This user guide provides an overview of using the EVAL-ADISMCBZ, including instructions for the motion capture board (MCB) hardware setup and software functions. The EVAL-ADIS-MCBZ supports a wide array of Analog Devices, Inc., sensor families (ADXL, ADIS, and ADXRS). It easily communicates with sensors and captures data by connecting the hardware to a PC and running the evaluation software. The graphical user interface (UI) of the software allows plotting and storing sensor data for postcapture analysis.

Evaluating the ADXL380 Low Noise, Low Power, Wide Bandwidth, 3-Axis MEMS Accelerometer
Product Detail
This user guide provides an overview of using the EVAL-ADXL380- BB-1Z (breakout board for the SPI variant of the ADXL380), EVALADXL380- BB-2Z (breakboard for the I2C variant of the ADXL380), EVAL-ADXL380-EB-1Z (evaluation board for the SPI variant of the ADXL380), and EVAL-ADXL380-EB-2Z (evaluation board for the I2C variant of the ADXL380) as a PC-based solution for evaluating the ADXL380 microelectromechanical systems (MEMS) accelerometer. These evaluation boards use the motion capture board (MCB) from the EVAL-ADIS-MCBZ platform for an easy communication and data collection using the graphical user interface (GUI). Go to the EVAL-ADIS-CBZ web page to download the software and its user guide, which details the installation process and the software features. This user guide gives an overview of using the ADXL380 evaluation boards available, detailing their functionality with provided examples where relevant.
Figure 1 shows the required hardware components for the ADXL380 evaluation system. The EVAL-ADIS-MCBZ is the controller board that provides a means of communication with the EVALADXL380- BB-1Z, EVAL-ADXL380-BB-2Z, EVAL-ADXL380-EB-1Z, or EVAL-ADXL380-EB-2Z evaluation board from the PC.
For full details on the ADXL380, see the ADXL380 data sheet, which should be consulted in conjunction with this user guide when using the EVAL-ADXL380-BB-1Z, EVAL-ADXL380-BB-2Z, EVALADXL380- EB-1Z, or EVAL-ADXL380-EB-2Z evaluation board.
