Hell0,
I need general guidance for this problem.
I am interfacing with a laser controller and need to provide a 0 to 10V voltage to control the laser power.
I am thinking about using fast pwm, filtered by a low pass filter, along with a 2x non inverting op amp configuration to get 0 to 10v.
I can live with 255 step resolution for this application.
My question is on using a transceiver/buffer to interface with the device, to isolate both circuits.
Can anybody help me with the selection of the buffer ?
