A data conversion device for converting analog data to digital data, or digital data to analog data, is composed of a data converter. and a mediator. Plural data groups are fed to the data converter that coverts the data, group by group, upon receipt of a request for converting a particular data group. If plural requests are simultaneously made, the mediator makes mediation among the plural requests to select a data group to be first converted and to set a priority order. A function uniquely corresponding to a combination of the plural requests is generated in the mediator, and the mediation is performed based on the generated function with reference to a preinstalled table showing a relation between the function and the request to be selected.
