A method for converting analog data to digital data is disclosed. The method includes operating an analog-to-digital data converter in a tracking mode to sample an input signal and in a convert mode to convert the sampled input signal after sampling to a digital signal. The analog-to-digital data converter is controlled with a controller to operate in different modes of operation by providing at least one step wherein the tracking mode of operation is controlled to initiate at a predetermined time to begin the sampling operation.
