Power saving standby operation mode with fast recovery RoHS compliant 40C to +125C temperature range 5 mm 5 mm 1.80 mm LFCSP package APPLICATIONS Condition monitoring Predictive maintenance Asset health Test and measurement Health usage monitoring system (HUMS) GENERAL DESCRIPTION The ADXL1001/ADXL1002 deliver ultralow noise density over The ADXL1001/ADXL1002 have an integrated full electrostatic an extended frequency range with two full-scale range options, self test (ST) function and an overrange (OR) indicator that and are optimized for industrial condition monitoring. The allow advanced system level features and are useful for ADXL1001 (100 g) and the ADXL1002 (50 g) have typical embedded applications. With low power and single-supply noise densities of 30 g/Hz and 25 g/Hz, respectively. Both operation of 3.3 V to 5.25 V, the ADXL1001/ADXL1002 also accelerometer devices have stable and repeatable sensitivity, enable wireless sensing product design. The ADXL1001/ which is immune to external shocks up to 10,000 g. ADXL1002 are available in a 5 mm 5 mm 1.80 mm LFCSP package, and are rated for operation over a 40C to +125C temperature range.
