Abstract

In a scalable driver device having a plurality of driver stages whose outputs are connected to a common terminal contact for providing a common output signal, drive parameters of the driver stages, individually or in groups, are so dimensioned that the difference of the edge rise times and/or fall times of the output signal from one active driver stage to the next driver stage to be activated is substantially equal to the difference of the edge rise times and/or fall times from a next activated driver stage to the one activated after that.
