Device for operating a vibrating unit (1) of a vibration resonator has a piezoelectric drive (2) that is connected to the vibrating unit and feedback control electronics (3). The latter excite the drive using a periodic signal, while the response signal of the drive is fed to the electronics. A peak compensation unit (4) has at least a suppression unit (5, 13) with a switching element (6, 14). The suppression unit is controlled by the electronics such that during a rising and or falling flank of the excitation signal, the piezoelectric drive is connected to earth.
