  • Sine/cosine analog track with electronic calibration
  • Diff. sine/cosine outputs with 1024 CPR (amplitude: 500 mV)
  • Position value of up to 16 bits through 6-bit interpolation
  • Quadrature signals with 1024, 2048, 4096, 8192, 16384 CPR
  • Index signal in phase with B low
  • 14-bit parallel position data output
  • Serial data readout in 1 μs cycles at 16 MHz clock frequency
  • SPI interface for configuration and position data output
  • 3.3 V-compatible SPI and I/O ports
  • LED current control for a constant receive power
    (50mA highside driver, sin2+cos2 or sum)
  • Permanent parity monitoring of the internal RAM bits
  • Alarm for configuration and illumination errors (end of life)
  • Temperature range from -40C to 110C
  • Small outline, 30-pin optoBGA package for SMT
