a question ADAU1452.
if I need 3 LEDs.... but 3 LEDs are already busy on the board, and exactly the MP11, MP12 and MP13 LEDs are already soldered.... and MP6, MP7 and MP9 are already busy as switches always on the board.. In this situation where do I connect my 3 LEDs? can I connect them in parallel to the LEDs on the board? (MP11, MP12, MP13)

ADI North America will be on winter shutdown starting December 25, 2023; perhaps another community member can assist you until our return on January 8, 2024.

Hello GeCo,

Are you using our Eval board, or you have your own hardware? If it's your own hardware, then attaching your hardware schematic would be helpful.

You can connect then in parallel if you're using an inverter like the one in the diagram below.

Do you want to have three other MP pins for your LED?

Explaining a little more about your needs will be helpful to assist you furtherly.

Regards,

Harish

thank you so much for your attention.
I attach an image of the card and diagram. I have nothing else.

I have to make a panel with three LEDs on it and I don't really understand how to connect the wires on the board.

Thanks again
