8-Bit Sine-to-Digital Converter Processor with Waveform Adaptation

iC-NG is a real-time vector-tracking sine/cosine-to-digital converter with an angle resolution of up to 256. The angle can be output via a parallel MCU interface (absolute), or as an encoder quadrature signal with index.

Features

  • Real-time interpolator with a programmable resolution of up to 256 steps/period
  • Calibration features permit adaptation of distorted sine/cosine signals
  • Output with A/B/Z incremental signals of up to 400 kHz, as a parallel 8-bit absolute vector or via a serial interface

Applications

  • Absolute and incremental angle interpolation from orthogonal sinusoidal input signals
  • Interpolating interface for MR sensors and optical analog encoders
