I'm new to the custom circuit design game, but I understand the basics of what I need. Here is my situation:
I have an audio amplifier that takes a 10k pot connection to determine the volume it needs to amplify at. I need to be able to control this 10k pot with a 30v relay output signal (or it can be an IR signal, if I need to go that far.) I was able to find the Maxim MAX5457EEE+ chip which appears to do what I would need. I would need to drive a bunch of relays that will take a 30v input and convert it to a lower voltage that the MAX5457EEE+ will underatand. I would need to design a custom PCB as well. I dont know how to do that. I can solder no problem, but I've never designed my own complete circuit before.... any help with this would be much appreciated. I already have a bunch of MAX5457EEE+ chips, but I dont have any of the other components (nor do I know exactly what else I need to get) but I do have the system that will be sending the 30v signal (1 for volume up and 1 for volume down) I need to control 3 amps, so there will be 6 30v triggers as well as 3 seperate mute triggers for a total of 9 (so I will be using 3 MAX5457EEE+ chips)
Thanks!
