Description
The iC-TW28 is a general purpose 10-bit application-specific 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 1024 increments per input cycle. Automatic calibration and adaption (correction during operation) of sensor offset, sin/cos amplitude match, and phase quadrature is provided. Additionally, automatic calibration of gain, offset and phase of the zero inputs allows for rapid commissioning.
