Abstract

A laser driver circuit comprising an amplifier device with a plurality of switchable subamplifiers, which can be or are connected to an output for connection of a laser, ith an analog switching device for switching of analog input signals, a plurality of analog inputs for the analog input signals, a plurality of control inputs for receiving digital control signals, wherein each switchable subamplifier has a switching device for switching the amplification by one of the digital control signals, a digital switching device connected to an input of each switching device for the selectable connection of the input of the switching device of each switchable subamplifier to a control input. Whereby each switchable subamplifier has an analog input, which is connected to the analog switching device for the selectable switching of an analog input signal to the analog input.
