Analog Devices accelerometers for predictive maintenance, test and measurement, and asset health applications

ADI's ADXL1001 and ADXL1002 provide ultra-low noise density over extended frequency ranges, have two full-scale range options, and are optimized for industrial condition monitoring. The typical noise densities of ADXL1001 (±100 g) and ADXL1002 (±50 g) are 30 μg/√Hz and 25 μg/√Hz, respectively. Both accelerometer devices have stable, repeatable sensitivity and are impermeable to external shocks of up to 10,000 g.

The ADXL1001 and ADXL1002 feature integrated full electrostatic self-test (ST) functions and over-the-range (OR) indicators with advanced system-level features for embedded applications. The ADXL1001 and ADXL1002 have low power consumption and are powered by a single power supply ranging from 3.3V to 5.25V. They also support wireless detection product design. The ADXL1001 and ADXL1002 are packaged in a 5 mm x 5 mm x 1.80 mm LFCSP package and are rated for operating temperatures ranging from -40°C to +125°C.

The EVAL-ADXL1001Z and EVAL-ADXL1002Z are simple evaluation boards that users can use to quickly evaluate the performance of the ADXL1001 and ADXL1002 vibration sensors. The EVAL-ADXL1001Z and EVAL-ADXL1002Z are specifically designed to be mounted on mechanical shake tables and are bonded by 0.8 square inch ultra-thick printed circuit boards (PCBS). With screw holes for rigid mounting to the shaking table.

The design allows users to evaluate the full performance range of the ADXL1001 or ADXL1002 vibration sensor without having to solder the device to a separate test plate. A simple RC low-pass filter with a -3 dB bandwidth of about 20 kHz is provided at the output. Components can be replaced to allow users to implement their own application-specific low-pass filters on the device output.
