Mixed-signal circuitry, comprising: an array of ADC units configured to operate in a time-interleaved manner, and each operable in each of a series of time windows to convert an analogue input value into a corresponding digital output value, each conversion comprising a sequence of sub-conversion operations, each successive sub-conversion operation of a sequence being triggered by completion of the preceding sub-conversion operation; and a controller, wherein: at least one of the ADC units is operable to act as a reporting ADC unit and indicate, for each of one or more monitored said conversions, whether or not a particular one of the sub-conversion operations completed during the time window concerned; and the controller is operable to consider at least one such indication and to control the circuitry in dependence upon the or each considered indication. |
