Abstract
An A/D converter system includes a first A/D converter with calibration circuitry. Also included in the system is an auxiliary A/D converter having a lower performance level than the first A/D converter. Circuitry is provided for temporarily switching an A/D conversion from the first A/D converter to the auxiliary A/D converter during short time intervals used for calibration of the first A/D converter. The rate at which the A/D conversion is switched is lower than the sampling rate of the first A/D converter.
