iC-MR3    13-Bit S&H Sin/Cos Interpolator with 2.5 V / 5 V Controller Interface - (preliminary)

Applications
  • Fast position decoding for safety-oriented encoder systems
  • Motor feedback systems
Features
  • Triggered 13-bit sine-to-digital conversion within 2 μs
  • Precision PGA for differential and single-ended signals of up to 500 kHz
  • Voltage or current input mode with signal monitoring
  • Adjustable signal conditioning for offset, amplitude, and phase
  • Input signal stabilization through LED or MR bridge current control of up to 50 mA
  • 8-bit parallel and serial I/O interfaces (BiSS, SSI, and SPI) with separate low-voltage supply
  • Absolute data interface (ADI: BiSS/SSI) for initialization
  • For position data of up to 50 bit with adjustable singleturn/multiturn data length
  • Position data preset using ST/MT offset registers
  • 12-bit A/D converter for temperature sensing
  • Special functions for safety applications (signal monitoring, sign-of-life counter, and extended CRC)
  • Current-limited, differential 1 Vpp sine/cosine outputs to 100 Ω
  • Device configurable through I/O interfaces or a serial EEPROM
  • Single-sided 5 V operation from -40 to +125 C
