Abstract
A circuit arrangement for driving a capcitive load comprises a control circuit (1), whose output is the collector of an output transistor (2). The collector is coupled through the gatesource path of a junction field effect transistor (5) and a resistor (6) connected parallel thereto to the capacitive load (8). The drain connection of the J-FET is connected to the supply voltage (Ub). The circuit permits rapid switching of the load while maintaining the current consumption relatively low.
