ADXL78:  Single-Axis, High-g, iMEMS® Accelerometers

Product Description

The ADXL78 is a small package (5 mm x 5 mm x 2 mm ceramic LCC), low power (1.3 mA current at 5V), single axis high-g iMEMS® accelerometer designed to sense shock and vibration at g-ranges of ±35g, ±50g, or ±70g. Three models are available and include AD22279-A-R2 (±35g), AD22280-R2 (±50g), and AD22281-R2 (±70g). These products are used in a variety of crash/impact detection applications that include automotive airbag crash detection systems as well as, medical, industrial, and sports equipment.

Applications:
  • Crash or Impact Detection
  • Vibration Control and Monitoring
  • Shock Detection

    • Features

    • Complete acceleration measurement system on a single monolithic IC
    • Available ±35g, ±50g, or ±70g output full-scale ranges
    • Full differential sensor and circuitry for high resistance to EMI/RFI
    • Environmentally robust packaging
    • Complete mechanical and electrical self-test on digital command
    • Output ratiometric to supply
    • Sensitive axis in the plane of the chip
    • High linearity (0.2% of full-scale)
    • Frequency response down to dc
    • Low noise
    • Low power consumption (1.3 mA)
    • 400 Hz, 2-pole Bessel filter
