iC-TW2    Programmable 8-Bit Sin/Cos Interpolation IC with EEPROM

  • Interpolator iC for position data acquisition from analog sin/cosine sensors
  • Optical linear/rotary encoders
  • Magneto resistive (MR) sensors/ecoders
  • Interpolation rate fully programmable from 1 to 256 steps per cycle (which equals to four times the value of true interpolation factor)
  • Latency less than 500 ns
  • Direct sensor connection, selectable input gain, input signal 10 mV to 1.5 V peak-peak differential
  • Max input frequency 460 kHz at interpolation rate <= 64, 230 kHz <= 128, 115 kHz > 128
  • Differential index gating input with fine adjustable offset (single ended by connection to VC)
  • Programmable index pulse output position and width
  • Output modes quadrature ABZ, up/down, increment/direction or 3 phase commutation
  • Programmable filter and hysteresis
  • Configurable startup behavior
  • On-chip Oscillator, E²PROM and power-on reset
  • Fully re-programmable with access to internal E²PROM to store setup and customer data
  • ESD protection and TTL-/CMOS-compatible outputs
