iC-MG    8-Bit Sin/Cos Interpolation iC with RS422 Driver

Applications
  • Optical and magnetic position sensors
  • Rotary encoders
  • Linear encoders
Features
  • Real-time tracking, no-missing-code interpolation
  • Selectable interpolation factors: x1, x2, x5, x10, x20, x25, x50
  • 100 kHz input frequency at highest resolution
  • Differential and single-ended PGA inputs
  • Variable input resistance enables current/voltage conversion
  • Signal conditioning for offset, amplitude and phase
  • Controlled 50 mA current source as LED or MR bridge supply
  • Encoder quadrature output via short-circuit-proof 20 mA push-pull line drivers (RS422)
  • Fail-safe counting assured by a guaranteed minimum phase distance
  • Index signal generation at selectable positions
  • Adjustable index length
  • Loss-of-signal indicator
  • Setup via serial EEPROM interface
  • Sub-system power switch offers reverse polarity protection for the overall system
