Description
The iC-TW8 is a 16-bit application-specific DSP interpolator for sine/cosine signals with automatic calibration and adaption of signal path parameters during operation to maintain minimum angular error and jitter. Angular position is calculated at a programmable resolution of up to 65,536 increments per input cycle. Automatic calibration and adaption (correction during operation) of sensor offset, Sin/Cos amplitude match, and phase quadrature is provided. Additionally, a 64-byte lookup table (LUT) is available to correct for residual harmonic distortion in the sensor signals.
