iC-MR 13-BIT S&H SIN/COS
preliminary
INTERPOLATOR WITH CONTROLLER INTERFACES
Rev A1, Page 1/44
FEATURES
o Fast 13-bit sine-to-digital conversion within 2 µs
o Precision PGA for differential and single-ended signals of
up to 500 kHz
o Voltage or current input mode with signal monitoring
o Adjustable signal conditioning for offset, amplitude, and phase
o Input signal stabilization through LED or MR bridge current
control of up to 50 mA
o 8-bit parallel and serial I/O interfaces (BiSS, SSI, and SPI)
o Absolute data interface (ADI: BiSS/SSI) for position preset
o Period counter of up to 50 bits with selectable
singleturn/multiturn splitting
o Position data preset using ST/MT offset registers
o 12-bit A/D converter for temperature sensing
o Special functions for safety applications (signal monitoring, life
counter, and extended CRC)
o Current-limited, differential 1 Vpp sine/cosine outputs to 100 Ω
o Device configurable through I/O interfaces or a serial
EEPROM
o Single-sided 5 V operation from -40 to +110 °C
APPLICATIONS
o Fast position decoding for
safety-oriented encoder systems
o Motor feedback systems
