Dear All,
I came across this schematic for opto-coupled output:
We have FPGA out 1.8V and resistor 100Ohm to regulate the current for diode from MOCD207-M.
I'm not sure how the other side works.
1. How works this circuit?
2. What is the purpose of the diode CDSU4148-HF?
3. What will happen if we put a series resistor with the diode?
4. What will happen if we remove the diode?
5. Does some one have experience with opto-coupled darlington output and can the darlington substitute the proposed circuit?
Best Regards.
