Laser driver circuit, method for controlling a laser driver circuit, and use

A method for controlling a laser driver circuit with analog inputs and digital control inputs and with an amplifier device with a plurality of switchable subamplifiers, the method comprising:

• assigning each switchable subamplifier to none or precisely one digital control input via control of a multiplexer;
• and
• assigning each switchable subamplifier to none or precisely one analog control input via control of an analog multiplexer,
• wherein the assignment of each switchable subamplifier to none or precisely one digital control input is stored via a register value, and wherein the assignment of each switchable subamplifier to none or precisely one analog control input is stored via a register value.

A laser driver circuit comprising:

• an amplifier device having a plurality of switchable subamplifiers that are connectable to an output for connecting a laser;
• an analog switching device for switching analog input signals;
• a plurality of analog inputs for the analog input signals;
• a plurality of control inputs for receiving digital control signals;
• a switching device of each switchable subamplifier for switching the amplification by one of the digital control signals;
• and
• a digital switching device connectable to an input of each switching device of each switchable subamplifier for selectably connecting an input of the switching device of each switchable subamplifier to a control input,
• wherein each switchable subamplifier has an analog input, each analog input being connectable to a different associated output of the analog switching device for selectably switching an analog input signal to the analog input.
