High-bandwidth accelerometer for industrial product designs

August 01, 2014 // By Graham Prophet
Freescale’s FXLN83xxQ accelerometer has been designed to capture acceleration information often missed by less accurate sensors commonly deployed in consumer products such as smartphones and exercise activity monitors: it enables intelligent algorithms to better perform fault prognostication for predictive maintenance and condition monitoring applications.

Housed in a 3 x 3 mm package, the FXLN83xxQ accelerometer features the highest bandwidth in its class (2.7 kHz) and is one of the first 3-axis devices to feature an operating temperature range of -40 to 105C. It operates from 1.71 to 3.6V supply voltage and has measurement ranges of ±2 g to 16g, selectable. With an analogue output, the device is universally compatible across a wide range of ADC-enabled MCUs. It has low power consumption for battery-operated applications, exposed leads for rapid solder joint inspection, and ten years guaranteed product availability via Freescale's product longevity program.

An evaluation kit, the DEMOFXLN83xxQ is available for the device, as well as four breakout boards (BRKOUT-FXLN8361Q, BRKOUT-FXLN8362Q, BRKOUT-FXLN8371Q, BRKOUT-FXLN8372Q) for a quick retrofit of the device. Freescale also provides the Xtrinsic Intelligent Sensing Framework for software development.

The FXLN83xxQ accelerometer costs $1.20 to $1.70 (1000).
