Abstract
A data converter () for digitizing an analog input signal and providing digital output data at one or more conversion cycles includes a logic circuit () for generating a data conversion diagnostic bit () having first and second logical states. The data conversion diagnostic bit toggles from one logical state to the other logical state when a conversion cycle is completed and when the digital output data from the previous conversion cycle has been read. The data conversion diagnostic bit remains at the same logical state when no conversion cycle has been completed or when no reading of the digital output data has been carried out.
