Low power consumption: 1.0 mA typical Power saving standby operation mode with fast recovery RoHS compliant −40°C to +125°C operating temperature range 32-lead, 5 mm × 5 mm × 1.8 mm LFCSP package APPLICATIONS Condition monitoring Predictive maintenance Asset health Test and measurement Health usage monitoring systems (HUMSs) Acoustic emissions GENERAL DESCRIPTION
The ADXL1005 delivers ultralow noise density over an The integrated signal conditioning electronics enable such extended frequency range and is optimized for bearing fault features as full electrostatic self test (ST) and an overrange (OR) detection and diagnostics. The ADXL1005 has a typical noise indicator, useful for embedded applications. With low power density of 75 μg/√Hz across the linear frequency range. and single-supply operation of 3.0 V to 5.25 V, the ADXL1005 Microelectronicmechanical systems (MEMS) accelerometers also enables wireless sensing product design. The ADXL1005 is have stable and repeatable sensitivity, and are immune to available in a 5 mm × 5 mm × 1.8 mm LFCSP package, and external shocks of up to 10,000 g. operates over the −40°C to +125°C temperature range.
