Patent ID: 8009710

Claim:
A laser driver circuit comprising: an amplifier device having a plurality of switchable subamplifiers that are connectable to an output for connecting a laser, said amplifier device further including: a plurality of switching devices each associated with a respective one of said plurality of switchable subamplifiers for switching the amplification by one of a plurality of digital control signals; a plurality of control inputs for receiving respective ones of said digital control signals; and a digital switching device including a plurality of multiplexers, each multiplexer for connection to an input of each of said switching devices for selectably connecting an input of the switching device of each switchable subamplifier to respective one of said plurality of control inputs, said laser device further comprising: an analog switching device for switching analog input signals; and a plurality of analog inputs for the analog input signals; wherein each of said plurality of switchable subamplifiers has an analog input, which is connectable to the analog switching device for selectably switching an analog input signal to the analog input.
