16-Bit Sin/Cos Interpolator with Automatic Calibration
The iC-TW8 is a 16-bit application-specific DSP interpolator for sine/cosine signals with automatic signal adaption and error correction to maintain minimum angular error and jitter. Angular position is calculated at a programmable resolution of up to 65 536 increments per input cycle. A 64-byte look-up table (LUT) is available additionally to correct for residual harmonic distortion in the sensor signals.
