An A/D converter calibration apparatus of the "skip-and-fill" type includes a set of operating condition parameter sensors (100) for detecting the current operating conditions, which are represented by parameters x1 . . . xN. The measured parameter are forwarded to an operating conditions change detector (102), which calculates a change measure and determines whether this measure exceeds or falls below a predetermined change threshold. A calibration control signal CTRL_SKP_RT is passed to a calibration control unit (104), which sets the background calibration skip rate to a high value if the measure exceeds the threshold an to a low value if it does not exceed the threshold.
