Zusammenfassung:Field of the Invention An integrated circuit containing a number of subcircuits is described. Each of the subcircuits contains a driver circuit for driving in each case one controllable voltage source on the basis of a reference value. The driver circuit has a memory unit for storing a reference value and a terminal for outputting a first reference value or for inputting a second reference value. A signal line, which is used for transmitting a signal, is connected to the terminal of the driver circuit of each of the subcircuits. The driving by the driver circuit is effected in each subcircuit on the basis of a common reference value that is transmitted via the signal line. Thus, the time needed for setting the reference values for all subcircuits is relatively short.
