The ADXL1003 delivers ultralow noise density over an extended frequency range and is optimized for bearing fault detection and diagnostics. The ADXL1003 has typical noise density of 45 μg/√Hzacross the linear frequency range. Microelectronicmechanical systems (MEMS) accelerometers have stable and repeatable sensitivity, and are immune to external shocks up to 10,000g.The integrated signal conditioning electronics enable such features as full electrostatic self test (ST) and an overrange (OR) indicator, useful for embedded applications. With low power and single-supply operation of 3.0 V to 5.25 V, the ADXL1003 also enables wireless sensing product design. The ADXL1003 is available in a 5 mm × 5 mm × 1.8 mm LFCSP package, and operates over the −40°C to +125°C temperature range.APPLICATIONSCondition monitoringPredictive maintenanceAsset healthTest and measurementHealth usage monitoring system (HUMSs)Acoustic emissions
