Abstract

A device for controlling a capacitive charge, in particular a piezoelectric actuator (2) has a signal generator (6) which is used to control a first end step (1) which is used to produce a discrete signal on the capacitive charge. Device has a second end step (3, 4) which is used to generate a continuous signal on the capacitive charge. A counter-coupling of a deviation of an actual discrete signal is produced by a continuous signal required on the capacitive charge.
