ADXL375-EP supports defense and aerospace applications (AQEC standard)
The ADXL375 is a small, thin, 3-axis MEMS accelerometer that provides low power consumption and high resolution measurement up to ±200 g. The digital output data is formatted as 16-bit, twos complement data and is accessible through a SPI (3- or 4-wire) or I2C digital interface.
An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to 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 extremely low power dissipation.
The ADXL375 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead LGA.
- Concussion and head trauma detection
- High force event detection

Evaluation Kits (2)
The EVAL-ADXL375Z is a simple evaluation board that allows quick evaluation of the performance of the ADXL375 3-axis digital accelerometer. The EVAL-ADXL375Z has two sets of 0.1 inch spaced vias, for population of a 4-pin and 5-pin header, for access to all power and signal lines. The vias or headers allow the evaluation board to be attached to a prototyping board (breadboard) or attached to the PCB in an existing system. Four holes are provided for mechanical attachment of the EVAL-ADXL375Z to the application. An external host processor is required for communication to the part.For evaluation boards that include a processor, please see the EVAL-ADXL375Z-M (Real Time Eval System for Digital Output Sensor).
The dimensions of the EVAL-ADXL375Z are 20 mm × 20 mm with mounting holes set 15 mm × 15 mm at the corners of the printed circuit board (PCB).
The iMEMS® Real Time Eval System is an easy-to-use evaluation tool targeting bench or desktop characterization of Analog Devices, Inc., inertial sensor products. The system consists of the inertial sensor evaluation board (ISEB), or main board, and a satellite board for any Analog Devices inertial sensor product. The ISEB connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The ISEB is connected to the satellite board through a ribbon 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 ISEB is an universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated.
The EVAL-ADxZ-M system contains the ISEB and the EVAL-ADxZ-S satellite. Also included is an USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite.
