I want to use an AD laser driver IC to control AC and DC current applied to the laser diode (VCSEL). All ICs I found are designed to control the cathode current of the laser diode.
The problem now is that I am working with an array of laser diodes, which has the cathodes of all the diodes wired to one pin, only the lasers anodes are individually addressable. I need to be able to control AC and DC currents for each individual laser!
Is there a way I can use, for example the ADN2871, to control the anode current of the laser by inverting the ouput current - or something similar?
Thanks and kind regards,
If you have further questions of how to use ADI laser diode drivers in your application, welcome to contact our central applications team at email@example.com. Thanks for being interested in our ADN2871.
