GENERAL DESCRIPTION
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/√Hz across the linear frequency range.
Microelectronicmechanical systems (MEMS) accelerometers
have stable and repeatable sensitivity, and are immune to
external shocks of up to 10,000 g.
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.
