概述

  • High resolution
  • Dual-axis accelerometer on a single IC chip
  • 5 mm × 5 mm × 2 mm LCC package
  • Low power <400 µA (typ)
  • X-axis and Y-axis aligned to within 0.1° (typ)
  • BW adjustment with a single capacitor
  • Single-supply operation
  • High shock survival

The ADXL311 is a low cost, low power, dual axis iMEMS® accelerometer that will measure acceleration with a full-scale range of ±2g. This complete dual axis accelerometer integrates signal conditioned voltage outputs on a single monolithic IC and can measure both dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity). The outputs are analog voltages proportional to acceleration. The typical noise floor is 300ug per root Hz at 3V operation, allowing signals below 2mg (0.1° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (10Hz). The ADXL311 is available in 5mm x 5mm x 2mm 8 lead hermetic LCC package.

Applications:
  • Tilt and motion sensing in cost sensitive applications
  • Smart hand-held devices
  • Computer security
  • Input devices
  • Pedometers and activity monitors
  • Game controllers
  • Toys and entertainment products
