ADXL1004 - MEMS Accelerometer

General Description

The ADXL1004 delivers ultralow noise density over an extended frequency range and is optimized for bearing fault detection and diagnostics.

The ADXL1004 has typical noise density of 125 µg/√Hz across the linear frequency range.

Key Features

  • Single, in plane axis accelerometer with analog output.
  • Full-scale range: ±500 g.
  • Linear frequency response range: dc to 24 kHz typical (3 dB point).
  • Resonant frequency: 45 kHz typical.
  • Ultralow noise density: 125 µg/√Hz.
  • Overrange sensing plus dc coupling allows fast recovery time.
  • Complete electromechanical self test.
  • Sensitivity performance.
  • Sensitivity stability over temperature within 5%.
  • Linearity to ±0.25% of full-scale range.
  • Cross.
