ADXL320:  Small and Thin, ±5 g Accelerometer

Product Description

The ADXL320 is a low cost, low power, complete dual-axis accelerometer with signal conditioned voltage outputs, which is all on a single monolithic IC. The product measures acceleration with a full-scale range of ±5g (typical). It can also measure both dynamic acceleration (vibration) and static acceleration (gravity)

The ADXL320’s typical noise floor is 250 µg/√Hz, allowing signals below 2 mg to be resolved in tilt-sensing applications using narrow bandwidths (<60 Hz).

The user selects the bandwidth of the accelerometer using capacitors CX and CY at the XOUT and YOUT pins. Bandwidths of 0.5 Hz to 2.5 kHz may be selected to suit the application.

The ADXL320 is available in a very thin 4 mm × 4 mm × 1.45 mm, 16-lead, plastic LFCSP

Benefits:
  • Two axis accelerometer in small (4mm x 4mm x 1.45mm) LFCSP package allows adding inertial sensing in
    space-critical handheld devices
  • Low power and wide supply voltage range (2.4V to 5.25V) for battery powered applications
  • Innovative circuit design provides sensitivity, zero-g bias stability over temperature - eliminates need for
    external compensation

    • Applications:
    Cost-sensitive motion- and tilt-sensing applications
    Smart hand-held devices
    Mobile phones
    Sports and health-related devices
    PC security and PC peripherals
