iC-TW8    16-Bit Sin/Cos Interpolator with Automatic Calibration

Applications
  • Sine/cosine interpolation
  • Signal conditioning with auto calibration
  • Linear and rotary encoders
  • Flexible incremental encoder systems
Features
  • Input frequency of up to 125 kHz
  • Differential sine/cosine input signal range of 20 mV to 1.4 V peak-peak
  • Binary/decimal interpolation factors from x0.25 to x16384
  • Post-AB divider [1/1 to 1/32] allows fractional resolution
  • Simple automatic one-pin calibration
  • Easy configuration: by static pins (for generic ABZ output)
  • Advanced configuration: 1-wire interface, 3 and 4-wire SPI (32 MHz), serial IC EEPROM
  • PWM or ABZ quadrature encoder output signals
  • Incremental ABZ output to 8 MHz (32 MHz edge separation)
  • Position and velocity read-out (32 bit SPI)
  • Sophisticated error handling and signal monitoring
  • Static 64 position LUT to compensate for arbitrary sensor distortions
  • Supply voltage range of 3.1 V to 5.5 V
  • Extended temperature range of -40 C to +125 C
