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.

APPLICATIONS

  • Audio and active noise cancellation (ANC)
  • Robotics
  • Wearables and low power motion detection

EVAL-ADIS-MCBZ User Guide

Features and Benefits

  • Plug and play rapid evaluation of the ADI MEMS sensor
  • Supports the broad range of the ADI MEMS sensor family
  • PC-based evaluation software with user friendly graphical interface
  • Self contained data capture with battery and SD memory card
  • On-board bluetooth low energy (BLE) module

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.
