Interpolator with A/B quadrature output that achieves resolution from 4.3nm to 34.5nm.

  • High resolution: 4.3 to 34.5nm (depends on the number of divisions)
  • High response speed: 400mm/s
  • DC offset, gain, phase automatic conditioning
  • 32 bit binary output by data request input (T14, T16, T17)
