Kit Overview

The Analog Devices EVAL-ADXL362Z-MLPEVAL-ADXL362Z-MLP is a complete system for real-time evaluation of the ADXL362ADXL362 micropower, 3-axis, digital-ouptut MEMS accelerometer. This system is accompanied by a graphical user interface (GUI) that facilitates evaluation of parameters such as power consumption, temperature coefficient, noise, and more. The system consists of a motherboard and a satellite board. The sensor is housed in a socket on the satellite board, enabling evaluation of multiple parts using one evaluation system.

The ADXL362ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 μA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode.

To order the complete system, order the EVAL-ADXL362Z-MLPEVAL-ADXL362Z-MLP which includes a motherboard, satellite board, accelerometer, and cables. Additional satellite board kits can be ordered using the part number EVAL-ADXL362Z-SEVAL-ADXL362Z-S. Satellite kit orders include a satellite board and an accelerometer.
